One of my ecommerce sites has really grown over the past few years and is now generating over $300k in credit card purchases a month with an average transaction value of around $200. All transactions are made online and we do not have a terminal. I haven't renegotiated my rates for a while and am looking for some advice on where to look. What kind of rates should I be shooting for? Right now I'm on an interchange plus program and want to stick with authorize.net as my gateway.
Any advice would be appreciated.
