I'm sitting on 3 platinum chests and 4 gold chests. Yes, that's all my slots filled. It was 2 platinum chests and 5 gold chests but I exchanged one of the golds for a platinum a couple days ago. Since I don't need anything in the bronze or silver chests I'm just discarding them as I find them. My park already has over 30 apprentice shop stands and I'm sitting on over 11 million magic. Not even worth the trouble any more. My goal is to get whatever Frozen attraction they stick in the gold and platinum chests without having to spend any gems to do it.
