I think it would be sensible to set up an Amazon account with your cousin's name and your home address. Fund it with gift certificates. That way, your credit card is protected, but you cousin can buy whatever they want and control their own account. To add gift certificates, s/he would need an amazon account in whatever country s/he has credit cards. Then contact Amazon and find out best method to send gift certificate to someone with US account. The fact that s/he is sending it to her/himself doesn't need to come up.

HarryT, clearly, this person wants books that are available in the AMERICAN catalog. Telling them to just suck it up doesn't really answer the question. They may not be able solve the problem, but certainly some tips and handy, helpful relatives, perhaps can overcome it.
