I would only accept the 4 major credit cards, paypal and maybe a check depending if I knew who the person was (like a local business or such)

Mastercard, visa, discover, american express.

Accepting Money orders, checks, and wire transfers is just stupid. It takes to much time to setup the transfer, make sure the funds are there, and sometimes there are some rediculous fees that are added on to the account.

If people dont have a credit card or some method of payment to do over the net... then they shouldnt be shopping on the net. They should find a local provider and write them a check monthly.
