online shopping w/ international credit card

hey,
i have been looking around for good hardware stroes online and havent been able to find any good ones which accept international credit cards. I have a credit card issued in jamaica and i cant order from Newegg, Googlegear, or most of the shops on pricewatch. I have run out of places to look, so i figured that you guys might have some sources. I would prefer a site in the US because my mailing address is in the US, so i can cut down on shipping! I am really lost!
