That pricing is the starting tier for us. We scale with your business and make sure that we're completely price-competitive as you grow. (One of the nice things about the industry is everyone has the same backend interchange costs, so it's possible to match anyone else's rates.) As well, other processor headline rates generally don't take into account a number of other read-the-fine-print fees which can add up to quite a lot.
Said another way, pricing should actually be a non-issue in your choice of processor.
