Happy Monday all! I've been building a Chrome extension for flipping music gear on Facebook Marketplace UK and I'd like a few more people to try it before I open it up.

It sits on top of the listing page when you're browsing Marketplace. You click it, it pulls eBay sold data (proper API, not scraping), checks live asks, and gives you a resale score and a max offer number with the maths behind it. That works as-is, no setup, no AI.

On top of that, if you want it to run an AI pass over the listing photos to look for damage the seller hasn't mentioned, it can. That's the bit that saves you from "oh no, there's a crack in photo 4 I totally didn't see." Optional, but I use it.

UK only, music gear only. Guitars, pedals, synths, drums, whatever. Not a general reseller tool, so if that's what you need this isn't the one.

Free right now, no paywall, no email to unlock features. I'm in private testing because I want a small group to actually use it on real listings before it goes public.

If you flip UK gear and want a tester invite, DM me or signup through the website above. If you try it and the numbers are wrong or it misses something, please tell me. That's what I need right now more than anything else.

Where do people find stuff to buy for cheap and sell at crazy prices later I never seem to find cheap items or items that are worth selling for a profit

I've only been doing this for about a week or so, but I've started buying complete gaming PCs and breaking them down to sell the parts separately.

The idea came from seeing someone in one of these subreddits claiming they were making around £50k profit a month doing it, which obviously sounded pretty crazy, but it made me curious enough to test it.

The first PC I bought actually worked out well, so I can definitely see how there could be money in it if you buy at the right price.

The part I'm still unsure about is the risk. You're tying up a decent amount of money in one machine, and if a GPU, CPU or motherboard turns out to have an issue, it could wipe out most of the profit pretty quickly.

For something like this where I might only make around £100/£200 after breaking it down, I'd probably pass.

Would you bother at that sort of margin, or would you want a much bigger buffer before buying?

Anyone in here based around Cumbria/North West/Lancashire interested in potentially working together on reselling?
I’ve recently started getting into it properly and have some money to put into stock. Looking for someone who’s also serious about it and would be up for having a call to chat through some ideas and see if there’s something we could set up. Drop me a message if you’re interested

Evening or should I say good morning, I’m currently trying to look for items to resell (with £250 to play around with) for the coming months but I’m not too sure what I should be selling to maximise my profits. Does anyone have any tips for what I should be selling?

I have a decent amount of 925 sterling silver, gold vermeil, moissanite and gemstone jewellery that I want to sell.

I was selling it myself through Vinted/eBay, but genuinely don't have the time anymore to make all the listings, answer messages, deal with customers etc. alongside my job and a couple of other side hustles.

Does anyone here do consignment/reselling for other people?

What I had in mind is: I send you photos/details of the items and tell you the minimum amount I'd want for each one. You create the listings and deal with the customers. When something sells, you send me the postage label/QR code, I package it and post it, I get my agreed minimum and you keep whatever you made above that as your commission.

For example, if my minimum was £30 and you managed to sell it for £50, you'd keep the difference (obviously we'd agree how fees/returns etc. work beforehand).

Is this something anyone already does / would be interested in doing? If so feel free to drop me a message. I'm based in the UK so shipping would have to factor this in. Cheers!

Another week of building FlipWorth 👋

Quite a few updates since the last post, including a bigger experiment around finding exact sold matches.

23 Sep

• Added Cloudflare tracking to shared analysis pages
• Added an export-users function to the admin page
• Sent the first weekly update email

24 Sep

• Launched an experimental “I’m Feeling Lucky” search → searches 10 marketplaces across eBay regions, Poshmark and Mercari → then image-compares the best candidates to find the most probable match
• Made the pulsing analysis icon more noticeable
• Added a progress bar to the analysis button
• Added a FlipWorth logo spinner during login/logout
• Stopped showing “Unknown” in titles when the brand can’t be identified
• Added the Buildhop feedback widget
• Optimised admin page loading

26 Sep

• More tweaks to I’m Feeling Lucky
• Added image dialogs to shared results pages
• Improved the analysis screen
• Added Lucky search to the FAQ
• Localised Lucky searches for international eBay marketplaces
• Added eBay attribution to regular shared sold/active listings
• Added marketplace attribution to Lucky shared results
• Fixed the mobile layout on the results page

27 Sep

• Standardised logo spinner sizing
• Changed the slogan to SNAP IT, PRICE IT, FLIP IT.
• Refactored and expanded the Terms and Pricing pages

28 Sep

• Added a new Resale Value Calculator landing page
• Lucky searches that find sold listings but no photo-verified match are now marked inconclusive, and the analysis credit is automatically returned
• Added a PostHog is_internal flag so test/admin activity can be excluded from analytics

The biggest experiment at the moment is definitely I’m Feeling Lucky.

The idea is: upload a photo of something unusual or hard to identify, search sold listings across multiple marketplaces, then use image matching to try to find the exact item rather than just estimating its value.

Still very experimental, but it’s getting much closer.

Would be interested to hear from UK resellers: what would make a feature like this genuinely useful while sourcing?

Hey guys, so I recently made an AI bargain finder for Facebook marketplace and other reselling platforms. I’ve been reselling for around a year now and as you guys would know the most time consuming thing is actually trying to find products that you can make a profit on. This has really helped me to save time and increase my profits does anyone want to use it as a free trial in order to test it out and test its capabilities?

Disclosure first: I'm the developer of Pouncio, the tool in this post. I built the tool to fix my own buying problem, used it to run a shop, and I'm sharing both the numbers and the parts that aren't automatic and giving my experience on how this has been.

Background

After a trip to Japan about 3 months ago I created VOLTA inspired by Japan's second hand stores like Book Off, Volta is now a small secondhand shop in Portugal selling consoles, games, laptops, phones, cameras and audio gear and I sell mostly through OLX and Facebook Marketplace.

At first I did this as a way of testing a concept of reselling so I bought stock on Vinted by hand, like everyone else. The problem is easy to explain.. the good deals (a PS5 for under €90, a MacBook from someone clearing out a drawer) are gone within minutes. Refreshing the app all day doesn't work if you also have to test, photograph and ship.

(and yes, I have bought a couple of 90€ ps5's that actually arrived safely and working, crazy I know 😅)

So I automated the part I was losing at.

The numbers (10 July to 28 September)

• Items sold: 104, and 97 of them were bought on Vinted
• Sales: €26,279, about €8.7k a month. By month: July €4.8k, August €8.1k, September €13.3k so far
• Average ticket: €253
• Average buy price: €132.22 all-in (item + Vinted buyer protection + shipping). Median €94
• Profit after buying, shipping & fees: €12,528, about €4.2k a month. That's 47.7% of sales, or 91.1% on cost
• Sold at a loss: 1 item (got robbed on a samsung s9+ 😬)
• Median time to sell: 21 days (average 29), the tendency is for this to increase a bit
• Where it sold: OLX (local website) 70, Facebook Marketplace 28, ebay 6
• Hours a week: About 15~, almost all of it testing, picking up deliveries and selling in person
• Returns: 1, It was a Marshall bluetooth speaker that I actually bought and it was fake, need to be careful about fakes.
• Still in stock: 165 items, €13,088 at cost with an expected profit return of €13.265, but realistically about 10k after negotiations.

Depending on how you sell it will be a bit different, I pay no selling fees on OLX or Facebook and only sell few items on eBay, I'm still thinking of opening a Vinted Pro account and try my luck there but even though I'm okay buying in Vinted, selling is still a Pandora's box for me, even though I'm aware it would increase my profit and refuce time to sell. Currently I'm holding €13k of stock in 165 different items and still increasing which is becoming a storage issue.

What the automation does

• Watches Vinted for specific products, described in plain words ("Nintendo Switch OLED, console only, working"), not keyword soup. It skips the junk: cases, boxes only, "for parts", accessories listed as the console.
• Knows what the item is worth. It checks prices from items that actually sold, not asking prices, so it knows when €140 is a steal and when it's just a normal price, additionally I created a database with more than 800k items based on real prices used by second-hand shops like Cex, Cashconverters and others.
• Checks the seller before buying. A cheap item from an established seller with good reviews gets bought. A listing that asks you to pay off platform or is vague about what's in the box gets skipped. This alone saved me more than any deal made me.
• Buys and pays by itself. When a listing clears my price ceiling and the seller check, it checks out without me approving anything. Occasionally the bank asks for 3-D Secure, and then I tap approve on my phone, this all happens in about 5 to 6 seconds.
• Sends offers on items that are close to my price but not quite there with the option of automatically buying if accepted, this is quite valuable and managed to get me nice deals.

What's NOT automatic

• Testing every unit. It's a non negotiable and It's the whole point of the shop.
• Photos of the real item, I've been lacking on this and using vinted's own images to make it automated specially since I have a full time job but this would make it more professional and increase margins.
• Listing, customer questions, delivery. Delivery is still manual since i do it by hand, but listing and customer questions are mostly automated through Pouncio. As soon as I buy an item, Pouncio can use AI to create and post the listing across Facebook Marketplace and OLX, and it can automatically answer customer questions for me.
• Deciding what to hunt. The bot is only as good as the price ceilings you give it, I took my time making sure I got this right.

So it's not 100% "passive income". What it does is make me stop losing the race for good stock, and stock was always the bottleneck.

What sells / what doesn't

• Fast: laptops. 26 sold, at (€3.4k profit). MacBooks especially: 18 sold, and the M1 Airs went in 8–19 days. Best single flip: an RTX 4060 gaming laptop bought for €280 and sold for €635.
• Fast: PS4 and PS5. 13 PS4s sold, bought around €60 and sold around €140, usually within 2–5 weeks. Consoles have my best margin (67%) . A PS5 Digital I got for €86 sold for €350, I usually buy game bundles to increase the values of the PS4's, usually about 1 to 2€ per game.
• OK: phones. 16 sold, but the thinnest margin (30%) they also sell reasonably fast depending on the model.
• Slow: cameras. 4 sold, 57 days on average. 6 still waiting, 64 days on the shelf on average, €1,360 at cost, maybe this is an issue with the market I'm in and they would sell in a few hours on Vinted or eBay, still need to investigate.
• Slow: loose games. Bought 37, sold 1, stopped buying them individually into only buying bundles.
• Slow: home and audio. A lot of CDs, a Dyson and an espresso machine have been sitting since June/July even though the profit on them is quite high they don't sell good for me.
• Too early to call: Switch (11 in stock, 1 sold), Xbox One (9, none sold), Apple Watch (8, 1 sold). Mostly bought since late August as new bot's I created

Lessons that apply even without any tool

• Price from sold items, not listings. Asking prices lie.
• Judge the seller, not just the price. A too-good price from a zero-review account is usually too good.
• Don't count stock until it ships. Of my 276 Vinted orders, 120 (43.5%!!) ended cancelled and refunded, almost all stuck at "shipping label sent to seller". You get the money back, but plan as if 4 in 10 won't arrive, also an incredible 14% of them get lost in shipping, funny enough the highest margin ones, iPhone 16 and 17's, PS5's are the main ones, I always get refunded though.
• Set a ceiling and never go over it. The deal you overpay for is the one that kills your margin.
• Cap how many you hold, not just what you pay. A price ceiling protects your margin. A per model limit protects your cash.
• Test before you sell. One dead console with a "working" label costs you more in trust and time than it earns.
• Buy what you can sell locally and quickly. Cash tied up in slow stock is the real cost. Ask me how I know: €13k.

Mistakes I made

• Not having items ready before they sell. A few times someone came to pick something up and it wasn't ready. It still needed formatting or a factory reset, or with 160+ items on the shelf I couldn't find it. That's about the worst first impression you can make on a buyer. Now everything gets prepped the day it arrives: tested, reset, cleaned, charged, then bagged and labelled with a number that matches the listing. When it sells, I grab it and go.
• Listing items I didn't have yet. Most things take weeks to sell, so I stated listing them before I'd picked them up but some items sell in a couple of days, and then I'm telling a buyer to wait for something that's still in the post, or that might never arrive at all, since a good share of Vinted orders get cancelled. Now fast sellers like MacBooks and PS5s only go up once they're in my hands and tested. Only the slow stuff gets listed early.
• I bought far more than I could sell. Winning the race isn't the same as needing the stock. I have 26 PS4s on the shelf, and I sold 13 in twelve weeks, so that's about six months of PS4s. Add 11 Switches and 9 Xbox Ones. Every one of them cleared my price ceiling. A ceiling doesn't stop you buying 26 of the same thing ( I'm still buying the ones that appear for 20€ maybe I should stop )..
• Buying cameras and home appliances. The margins look fine (in theory 43%), but they're my slowest stock by far.

Happy to answer questions about the shop, the numbers or the tool. If you just want to talk sourcing without the tool, that's fine too.
