There are definitely better deals out there than Worldpay, so you're wise to shop around. I would get quotes from 3 or 4 banks before making a decision - most quotes are for your specific business, so what might be cheaper for one person may not be for another. Protx is cheaper for processing payments, but if you do a bit of research you may find they have had some reliability problems in the past if I remember correctly, so check that's ok now before you sign up. Using Protx or any of the others that charge a fixed amount per transaction rather than a percentage can save you a lot compared to Worldpay.
