Sounds fishy indeed... Is it the seller that is asking for this, or AliExpress?
I've probably placed an order every two weeks for the last 3 years... The worst that happened was when I ordered a SD2IDE adapter and the shop contacted me saying their selling price was too low to include shipping and required to pay an extra $0.80 or something like. Which I did and received the item two weeks after... Other than that when I order a single item for less that $2-3 you have a high chance of never receiving it; that's why I always take their "Choice" or Bundle option...
