What our readings say: 1 of the 7 reading-days a verdict needs, and none in the last 7 days.

AliExpress prices this listing at 105.86 CNY. The $15.90 above is that figure converted by their affiliate API. AliExpress’s own site converts at a slightly different rate, so it may show a few percent less — the CNY number is the one neither of us converted.

The price on AliExpress may have moved since our latest reading, 16 Oct. Purchase happens on AliExpress, under their terms — we never handle payment, and we earn a commission at no extra cost to you.

Seller lists it at $28.39 — a claimed saving of $12.49. AliExpress does not verify that figure, and 5.7% of the listings we track make a claim in the same 40-49% range, so on its own it means very little.

How this works

About this product

We have one reading of this listing’s price, taken on 16 October 2026, at $15.90. Full specifications are on the AliExpress product page.

Outdoor Furniture

How this compares to everything else we track

We show 52,325 products, one per title, in Home & Garden. At $15.90, it sits above the middle of that category, which is $11.21 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 44% off. Only 8,432 of the products we track claim a discount that large — 5.7% of the catalogue sits in the 40-49% band, so this one stands out. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 2 orders for it. For comparison, the median listing we track in Home & Garden reports 24 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.

We have recorded this product’s price on 1 separate day since 2026-10-16, and it has not moved once. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.

If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
