Aliexpress dont pay anything to the seller until transaction is done, is like an escrow service. They send the money when you confirm goods received, or after the delivery period (you get emails reminding you to say if is something wrong). Seller usually take picture of the box, weight, boxing and stuff, aliexpress require them. 

I still think is a scam, but is not that easy for a seller to get $ from you.

That’s right. Ordered a too good to be true hot swappable mechanical keyboard and to no surprise I received nothing. The seller marked it as sent but never updated the package info. It was obviously a scam and I got my money back without any problems.
