In app purchases allow you to purchase virtual furniture and decor to play with. You can use the item 5 times before the item disappears from inventory. That's the rule. Unfortunately, they take away your most used items sooner as to force the player to purchase the item again and again. When you send them an email requesting your items be replaced, they ask for a screen shot of the item, and you never hear anything again. Do not use in-app purchasing for this game. Use game credits only. It's a scam for real cash.
