just to be sure that I fully understand everythingyou said about this method, I must :

1) Order the product I want
2) Order a product in same category with same weight (with a different Amazon account on a different address of course)
3) When the main product comes, I contact Amazon support to tell them that when I opened the box, a different item was here
4) They will ask me to return the item, so I will return them the cheap item
5) After few days/weeks, they will send me replacement/return

Spot-on.

Great, thanks !

I just don't understand ont thing :
About the wrong item with the second account, is it possible to make it delivered in Amazon locker ? because it's if in Locker, I can't tell that I haven't received it or empty box (my product has 500g weight)
