If I use the Upgrades plugin, can I have different packages?
Bronze (cost 1 credit)
Silver (cost 2 credits)
Gold (cost 3 credits)
The silver package would include everything in the bronze package, plus extras, the gold package would include everything in the silver package plus extras. So, for example, a single plugin could be available in all the packages, the user would just pay for the package they want.
Alternatively, is it possible to give a credit price to individual items (plugins/themes/webspace), but also have a price on a collection of items?
Does this make sense?
