Hi! I like this add-on, but would like to request a slight addition. I'd like to be able to add my own 'product' to the list, but buying it only takes the credits from the balance and sends admin an alert saying "username purchased product". For example, our forum has a Minecraft server, and we want to sell Minecraft items for forum currency using this framework. All I want is for users to be able to find what they're looking for in the store, 'order' it, and have that order send an alert to admin, who can then grant the item. I'm no expert, but I think for coders like you this should be a 5 minute job.
