Maybe I'm missing something, but the fees seem way too high for this to be a viable option for anything of scale. Even PayPal's fees are lower, and I get credit card fees of only 2.15% + $0.25 from a company offering a similar service. Yes, Stripe is beautifully designed and simple to use, but since I'm already setup somewhere else with significantly lower fees, I don't see the appeal. Are they specifically targeting small developers?
