We show 13,475 products, one per title, in Sports & Outdoors. At $39.00, it sits above the middle of that category, which is $6.71 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 50% off. So do 54,745 other products we track — 36.5% of our whole catalogue claims a discount in the 50-59% band. At that frequency the figure is a listing convention rather than a signal. 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 2 separate days since 2026-09-12, 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.
