1) He is pushy and is ordering large quantaties of items on two different credit cards.
2) He is in Tangier but is ordering from TX.
3) Doesn’t want proof of what the shirts look like.
4) Someone else will pick up.
5) Did not negotiate the price

The types of scams he could be running are ID theft, using stolen credit cards, getting the shirts and disputing the charges on the credit card saying he didn’t receive.

The big sign is that he says he is in Tangier, has an address in ID, and orders from TX. Are there not any shirt making companies in Tangier or ID?

I would guess that the cards are stolen and you will receive credit card chargebacks from the banks for the transactions.

As a side note to the person saying ask for a cashiers check from a reputable bank: Those checks can be counterfeit as well. There really is no sure fire payment method any more.

If he does, in fact, come through with the bank cashier’s check, then I’d have him sign a document stating that, since he declined proofing the shirts before delivery, he has waived his right to return any of the shirts or demand a refund whether full or partial.
