@mherrmann’s article on PayPal vs Stripe is worth reading:
…offering PayPal was a good decision: Even though Stripe is the default option, two thirds of fman purchases are now made with PayPal. From feedback, I know that some people simply can’t pay by credit card. Thus, offering PayPal significantly increases fman’s (small) revenue.
I recall @andrey having a similar experience with PayPal.
