Create a plugin that can be embedded in any eCommerce website in which on the checkout page, there will be a button asking them to Help for a cause. Once they have click on the button, a pop up window will appear with a Donate button and a No thanks (link or button is fine). Once they have clicked on the donate button, it will direct them to PayPal. Please take note it needs to be a fixed amount of 25 cents (foreign currencies should be automatically converted to my currency - Php).

As soon as they have completed the Donation, they will be directed back to the Pop up window showing a "Thank you" message and a button that will prompt them to continue their purchase. I should also receive a notifications about the donation information.

I will be using this simple plugin for my own site only and I will never have it for sale.

Anyone can start now?
