Been using it for a while

I really appreciate the efforts in making this plugin. It does really work as expected. There is a bug though which I managed to fix, see Support.
The plugin is extremely easy to understand and to modify. I have added new admin pages and modified the sql tables. I found the code structure and logic well organised.

I could also make the payment amount a little more dynamic. Instead of dictating a fixed price, I could get live prices from MySQL table.

In total, I recommend this application because it works as expected and can do more with a little coding ??
