When Stripe entered, people stopped caring about the cost of payment processing. I don't work in the industry anymore, but Stripe became rather popular at the time where I worked on online payments. We looked at it, because the Stripe API and services are really nice, but the cost is just insane.

We where never even close to 2.9% on credit cards, and we'd certainly never consider paying 30¢. Part of that is working out of the EU, that caps your credit card fee, so around 1% and 0.10EUR per transaction is closer to the standard. Then you can start negotiating lower raters from there, depending on the number of transaction you make.
