I've never seen a tool with as little frills as Trolley. You make payment links, products, digital downloads, subscriptions, etc. and it gives you a link.

That's it. No fanciness, and admittedly no advanced features, but it's got a very low fee and a very simple interface.

If you need cheap payments, or want a replacement to something like PayPal, check it out.

Dead simple, cheap, and functional. I've got nothing to complain about.
