How should I better monetize a simple PayPal tool?
In this case, I built a little PayPal tool that helps users pay the PayPal fee for their recipients. It's a cool, simple idea -- I put it on Flippa (https://flippa.com/5410502) but am thinking of how to improve on it if the auction doesn't meet the reserve.
Any good ideas for building up and monetizing such a minimal site?
Thanks!
