Ignoring the ~2.9% of Credit Card Processing Fees ( on average it would still be higher than 2.9% ), I dont see how they charge 10% for their services is exploitive jerks.
Changing the fee from 3%-5% total to 12.9% (17% on paypal!) total when you already have a large customer base there, meaning you'd have to painfully migrate them to another provider, is not a nice thing to do in my eyes.
And also why I'm working on completely migrating off.
