Too good not to share! A couple days ago this tip was left in the comments on one of my blog posts:
Candy Land Castle Game (my kids had this when they were little I think I sold it for .50 at a garage sale 🙁
I looked the game up on Amazon, and there are 4 new games listed, with the lowest price at $190!
Here is a list of completeds from eBay. If you find a game that is incomplete, it looks like you could also do okay selling it for parts.
