Ever had the problem if you accidently bought a iteam in game that you did not whan't . Well my idea is adding a text box say if you would like to buy that iteam or not . pritty much a yes or no type box added to the game for the bazzar and the hall of heros.

As an example of this is if a player is say a 3* and is geting 4* recipes and accidentally clicked the wrong recipe. Then that person would be out of crowns and then they have to go get more crowns and they also have a recipe that they did not whan't and can't sell cause it's bound .
