AliExpress 11.11 sales are mostly bogus

It is especially bad with delivery services: restaurants double their offer prices, only to then advertise them with a 50% discount.
Also, it's not a great place to get a good price on items where demand outstrips supply, like SBCs and mini PCs. You're better off getting them directly from the supplier or through their distributors.
I know as I operate a youtube channel and website (cheerful.cheap) and each 11.11 they send me a bunch of coupons.
