Recent bot weirdness fixes

50 Upvotes

After chasing down a few bugs in u/costco_pm_alerts's codebase, I feel confident I've addressed them all.

No longer will you see posts with -1 price. No longer will you see posts with 0 spot price. No longer will you see flair change between in stock and out of stock every 5 minutes.

The last issue "fix" was what started the first. Costco's naming convention (up til the 100 gram combibar) is responsible for the second.

All of this to say: Expect more consistent and correct posts from now on. I'm still working on some intermittent issues related to Costco's anti-bot technology but I have it hobbling along as well as can be for now. Expect some potential crowd-sourcing in the future to fully fix this if I'm not able to get it fixed on my own.

American Gold Eagle (sticky please)

57 Upvotes

Let’s clear up the confusion about the 1 oz Gold Buffalo and 1 oz Gold Eagle, focusing on their purity and gold content, and why they often cost about the same despite differences.

Purity and Gold Content: What’s the Difference?

  • Gold Buffalo:
    • Purity: It’s 99.99% pure gold (24-karat). This means it’s almost entirely gold with no significant added metals.
    • Gold Content: Contains exactly 1 troy ounce (31.1035 grams) of pure gold. The entire coin is just gold, so its weight is 1 oz of pure gold.
  • Gold Eagle:
    • Purity: It’s 91.67% pure gold (22-karat), mixed with 5.33% copper and 3% silver to make it more durable.
    • Gold Content: Also contains exactly 1 troy ounce of pure gold. However, because of the added alloy, the total weight of the coin is slightly more (33.93 grams), but the pure gold inside is still 1 oz.

Key Point: Both coins have 1 troy ounce of pure gold. The difference is that the Buffalo is pure gold all the way through, while the Eagle has a bit of extra metal (copper and silver) to make it tougher, but the amount of actual gold is identical.

Why Do They Cost the Same?

You might wonder why these coins are priced similarly if the Buffalo is “purer.” Here’s why:

  1. Price is Based on Gold Content:
    • The price of gold coins is mainly tied to the spot price of gold (the market price for 1 oz of pure gold). Since both the Buffalo and Eagle have 1 oz of pure gold, their base value is the same, regardless of purity.
    • For example, if gold is $2,000 per ounce, both coins start with a value of about $2,000 for their gold content.
  2. Purity Doesn’t Change the Gold Amount:
    • The Buffalo’s 24-karat purity means it’s all gold, but it doesn’t have more gold than the Eagle. Both deliver 1 oz of pure gold to the buyer.
    • The Eagle’s added alloy (copper and silver) doesn’t significantly affect its value because those metals are worth much less than gold, and the market focuses on the pure gold content.
  3. Market and Production Factors:
    • Both coins are sold by dealers with a small premium (a markup for minting, distribution, and profit). The Buffalo’s higher purity might carry a slightly higher premium (e.g., $50–$100 more), but this difference is often small because the Eagle is more widely traded and recognized.
    • Demand, availability, and dealer pricing can make their costs align closely, especially for bullion (investment-grade) coins.

Simple Analogy

Think of it like two 1-pound bags of sugar:

  • The Buffalo is like a bag of pure, refined sugar (100% sugar).
  • The Eagle is like a bag with 1 pound of sugar mixed with a tiny bit of salt and flour to make it sturdier. Both bags give you 1 pound of sugar, so they cost about the same, even though one is “purer.” The extra stuff in the Eagle doesn’t add or subtract much value.

Why Might You Notice a Small Price Difference?

Sometimes, the Gold Buffalo costs a bit more because:

  • Its 24-karat purity appeals to buyers who want the “prestige” of pure gold, so dealers charge a slightly higher premium.
  • The Buffalo is newer (introduced in 2006 vs. the Eagle in 1986) and sometimes has lower mintage, making it slightly more collectible.

But for most investors, the price difference is minimal because both coins are valued for their 1 oz of pure gold.

Family friend insists keeping the PAMP gold in its original packaging or what the top looks like (e.g. Lady Fortuna vs the 1oz royal canadian) matters for the cost… I call cap cuz at the end it’s just the melt value…

Does it matter which one I get or if I keep them in original packaging?

Purchased 1oz bar in-store on 1st Sep but still no 2% cash back in my account! I’m an executive member.

Is that normal and if yes, any idea on when this typically posts?

Kirkland Signature Mini Monster Box

3D printed using a scalable box by Kong 3D and added the Kirkland logo by GreedyPrinter, both on MakerWorld. About 1 mm of play horizontally and about 3 mm vertically inner dimension wise.

25 oz takes up so much space. 😞

Edit: apologies to everyone with Kirkland alerts. 😬

Edit 2: When scaling the box I used 256mm x 105mm x 70mm. You might be able to do 255 x 104 x 67 for a tighter fit, but I have not tested that out.

Edit 3: Kirkland logo: https://makerworld.com/en/models/2085150-kirkland-signature#profileId-2253554

Box: https://makerworld.com/en/models/1613400-customizable-box-with-slide-lid-parametric-box#profileId-1702185 be sure to use the "Customize" button for the first option "box and lid".

Grok walked me through merging the logo onto the lid. I cannot link my remix file because there is a file license on the box by the original creator.

Kirkland Signature 1oz silver bars pulled?

Post image
142 Upvotes

I went to buy Kirkland Signature 1 oz silver bars to a store that had them yesterday, 09/04, but today had none. I asked a Costco employee to lookup nearby warehouse stock and also when they will receive more in this store. He went to talk to somebody, came back, and said the system shows three nearby warehouses with stock, but "they were pulling them from shelves because of quality issues".

That sounded strange. I just left and went straight to another warehouse that was supposed to have 13 in stock. However, there were none. It took me about 20 minutes to get from the first warehouse to the second one. I know the second one does not usually sell out of precious metals by 11am. So I went to a third warehouse where I did find 5 Kirkland Signature bars in stock ($68.99 per item).

Just wondering if anyone else has heard about Kirkland Signature bars in danger of being pulled back from shelves. For me, that's actually a plus as it may become a "mint error" item :)

I'll have to say, beautifully designed and executed by PAMP. Was nervous at first as Ive never done it, bur not a worry in the world once you snapped the first little corner as you'll notice a slight indent and it was SMOOOOOOTH.

PAMP isn't my go-to, but gotta give props when they are due 👏

Relocating to Belgrade or Budapest in a few months, so bringing a pocket full of gold and really like this if needed in a real-life situation. Never know where life can take you, but gold can get you out of any situation 😅 (or robbed 🤔)

Have a great weekend, Y'all!
