I've been having a good time finding ways to separate students from their GP. For now, I've created a store using Google Forms, but it isn't database driven, so it is a lot of work on my part. It would be nice if there was a feature built into Classcraft that would allow teachers to stock a store with items that can be purchased. The teacher could add a photo of the product, a title, brief description, and cost in GP, etc. Students can add items to their "shopping carts" and when they checkout, their GP are adjusted accordingly. I can see so many possibilities with this.
