Trust me. Don't even mess around with that. You can get yourself into a whole lot of shit. You will get the fbi as well as every other police agency at your house. They will raid your house, take everything that means anything from you and then press charges.
This happened to me, and I wasn't even guilty of it (long story, but I was set up for it by someone I know.) Police do not fuck around when it comes to credit card fraud.
Sure, you could get away with it if you bought something just a few times, UPS'd it to a building where no one lives at or is away, and kept it under $300 dollars (depends on where you live.. but in some places once you charge over $300 it is considered a felony offense.)
Also, take to mind that if you use a computer to buy something online then the ip address is stored with the transaction. Which means that the owners of a card could view their transactions and see that a purchase was made that they are unaware of. They can call up the company that sold it to you, find your ip address as well as any other data they saved, hand that over to law enforcement, and then law enforcement can easily trace it to your house.. Unless of course you are masking your ip.
Your best bet would be to do it through a public library or something.
Multiple transactions from the same card will trigger alerts. If you got away with it once, then leave it at that. Because if you kept on using the card you will get the police waiting for you at that place you've been shipping to. You could send it to different addresses each time.. but still, FBI is not dumb. they can pick up on patterns relatively quickly.
So after all that, if you think it's worth it. Go ahead. But I am telling you from my personal expereience on both ends of credit card fraud. It's just not worth it and plain stupid.
