Modify donation plugin to add to price

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.2.4
-- PHP version -- : 5.4.32

Is it possible to modify the donation plugin so that it will add to the price of a parent product instead of overriding it? Any suggestions would be appreciated.

Hello,
Sure, you'll just have to check in your new donation plugin that your product HAVE a price, and if it does, you'll just have to add the "Amount" custom field value to it's price.
