fyi: apparently that's only a welcome (e.g., first-time user) offer. As soon as I logged in, it changed the price to ~11usd per piece.
Yeah, typical aliexpress misleading BS. I have yet to buy something on AE and 1. Pay the price initially shown (it’s always more) 2. Actually use one of the dozens of coupons it assaults me with every time I open the app.
