Edit: found a solution!
[Show spoiler]Hi,
I am aware I am probably violating some rule and that this is not the right place to ask, but I don't know any Americans, but I need help from an American:
I want to purchase a film collectible from an American online marketplace (Mercari), but they don't accept my credit card because it's not registered in the United States (I am from the Netherlands).
Can someone perhaps purchase the item for me? I have my own US address/locker, so you don't have to receive and forward anything, just make the payment.
I will, of course, send you the funds in advance.
Let me know if you're willing to help me with this; it would be GREATLY appreciated as it is something I have been looking for for several years.
