I don't want to use paypal. Does anyone have a suggestion on using a payment processing center that offers FREE TRIAL? Please let me know.
Plimus.com do offer free sign-up and I believe that sort of amounts to a free trial. If you don't like it, you can simply stop using it without consequences to you. Fees are only deducted when there is completed sales.
You shouldn't have to pay to join these sites. What you usually pay for is the transfer of money to your bank account, which is a small fee so the site can make money.
