Looks like a nice Christmas present is on the way!
You mention in the rules that an achievement can be granted for a purchase of a product or package… does this by any chance also apply to donations? If so, you’re going to solve a big problem for me. 🙂
I like your example about getting an achievement for buying a tshirt… it would be super cool if we could reverse that. Meaning if they get an achievement be able to give the member something (like a tshirt)! In this case maybe have the ability to issue a credit to the member account or allow them to make a one time free purchase etc. Think of that “Super Helpful” badge being able to give them a prize as well.
