Does anyone have any opinions on Authorize? Any good/bad experiences with them? I am thinking about switching over to them.
Authorize.Net is NOT a Payment Processor. They are a payment gateway. That means without a true merchant account to go along with it you can't use them. If you're in the US you can get a merchant account and an Authnet account to go with it. Authnet is very reliable and easy to use. As a payment gateway I highly recommend them. They're number one for a reason.
