Yes, except with credit cards. Card gets through but usually gets charged back 30 or more days later. They always want you to wire money to the shipper. This is a scam that is currently in vogue, and they get their victims from your website. If you bite once, they will generally follow-up with another very quickly, usually for a larger amount. Any time they want you to send any money anywhere, it is a scam. They don't want your merchandise (which can be traced through shipping), they want your money (if it is cash, wire, or western union the trail run cold fast). Always make sure Names, Addresses, and cc numbers match, call the cc company to match names on cc. For big tickets they will use multiple cc, sometimes with consecutive numbers. The bottom line is that if they know you won't play, they cross you off their list.
