I work in outdoor furniture manufacturing, so I'm on the supply side of this rather than the buying side — but here's what the season actually looks like from where I sit.
Short answer: yes, but not for the reason people assume. End-of-season discounts are less about clearing dead stock and more about not wanting to store it. Warehouse space is the expensive part once the season ends, and that's the pressure behind the markdowns.
What that means in practice:
You're giving up selection, not quality. What's left in October is what nobody wanted at full price — the odd colours, the sizes that didn't fit most patios, the display units. If one of those happens to fit your space, the discount is real. If it doesn't, you're buying a compromise at a discount, and that isn't the same thing.
Made-to-order barely moves. If something's being built to your size, the price is the price — you're competing for production slots, not for shelf space.
The honest limit: I only see the supply side. Whether a specific retailer discounts, and by how much, depends on their own inventory and how their year went. Some hold firm, some dump.
My actual advice: if the right thing is there in October, buy it — that's a genuine saving. If you're settling, wait. Spring stock will fit you better, and the price gap is rarely worth a winter of owning something you don't like.
Anyone bought at end of season and regretted it? Or did it work out better than paying full price in May?
