The Cash Shop Hustler just had [item=Get Stuffed!] for 9 CSC. I think it's trying to discount the official price, which is not in CSC like other Cash Shop items that appear there. Before this most recent update, Loyalty Shop items were going for 50 CSC each, which was already super affordable, but 9 CSC seems way too low now.

[edit] "Can I interest you in a for only 12 Cash Shop Credits?"

omg yes! I was wondering why these books seemed to be priced so low- discounting that 'official price' makes so much sense explaining it
