if your buddy is that nervous, simply tell him to get one of those cc's that you can get from like walmart and use that for seed orders... you don't have to register them with a real name of anything from what i've read...
but saying this, i order from the tude probably about two times a month and have always used my visa debit card and have never had an issue or anything, and the statement on my cc simply says attitude gifts, so if anyone were to see it, they'd no clue as to wtf you had really ordered from them..
