I had this happen to me one time with a xbox 360 parts website. I had been there before but I googled the name because I wasn't sure of the exact address.
SO I get ready to check out and I see the ship to address is someplace I have never heard of.
So I edit the guys mailing address to say
Please contact me at wjp09 aim
I got logged into your account
we need to fix this
Then the next day I was in a chat with the guy and a tech from the site lol
