What our readings say: 3 of 7 reading-days recorded. We judge a seller's discount only after 7 separate days of our own readings.

The price on AliExpress may have moved since our latest reading, 8 Nov. 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 $834.88 — a claimed saving of $208.72. AliExpress does not verify that figure, and 20.9% of the listings we track make a claim in the same under 30% range, so on its own it means very little.

How this works

About this product

We have 3 readings of this listing’s price since 5 October 2026, from $475.50 to $626.16. Full specifications are on the AliExpress product page.

Metal Processing Equipment & Accessories

How this compares to everything else we track

We show 52,649 products, one per title, in Home & Garden. At $626.16, it sits above the middle of that category, which is $11.17 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 25% off. That is modest for this catalogue, where 30,848 products (20.9%) sit in the same under 30% band and most of the rest claim far more. A small claim is at least a plausible one. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

We have recorded this product’s price on 3 separate days since 2026-10-05, and it has moved 1 time in that window. 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.
