I've been researching UK PSP's we can use in conjuction with our Barclay's merchant account, as ePDQ is extortionately expensive. So far top of the running seems to be Protx, followed by Velocitypay. Does anyone have any experiences (positive or negative) on these to recount, and are these related in particular to the type of e-commerce operation you are running? We would be averaging about 300 transactions a month, with an average transaction total of £200. It seems we'd be significantly better off by switching from ePDQ. I'd appreciate your comments.
