Easy to use Paypal plugin

I searched a lot for wordpress paypal plugins. Most were bulky and not meeting all my needs. I was building a website for a non-profit and needed to accept donations online with paypal, with pre-defined or custom amount. Sounds a simple need but lot of paypal plugins did not have this feature. I landed on this plugin and just fell in love with it!

Very easy to set up. Great customization of the form and its styles. Amazing support from Graham who wrote this plugin! And a very affordable and deserving price. What else do you want in a plugin?

Thanks to Graham for building this awesome plugin!
