It's fair - a bit more expensive than you could get doing it yourself. I think if you shop around, you can 2.2% for Visa/MC and 20 cents per transaction even with no credit or volume. The question if it's worth it is how do they handle refunds, cancellations, and most especially - expired credit cards. In a monthly service, you might lose more to expiring CC's than to cancellations! People's cards go over their limit, get canceled, or simply expire. I was surprised when I started seeing monthly credit card attrition numbers, it can brutal. So if Amazon lets customers cancel without you/your support team doing anything, that's valuable. If they let you offer "no questions asked refunds" where the customer can get it themself - that might be valuable. And biggest of all - if you can define an automatic process for dead CC's, that'd be really valuable. If Amazon would check if a CC verified, then automatically try again right away if it didn't, then again the next day and day after, then sent a series of 3 emails - if they offered something like that, that'd be phenomenal. I'm going to doubt they do though... So their prices - competitive enough. You'll want to make sure you're not held hostage to them once you start using them, which I suspect you are. And does someone need an Amazon account to sign up? Big question there. Depending on what value they add, they might be worth using. But only if they don't hold your customer data hostage if you want to leave as you grow.
