Purchasing items with coins

In my opinion the shop need to be " renovated and expanded "and hold more items that we can purchase using either gold coins or for those who can't purchase coins from PayPal or iTunes, perhaps some kind of extra currency that is offered to players as prizes for reaching certain targets or doing certain things ingame.

Some people may think that it defeats the purpose of the game, taking the easy way out if you will,but sometimes some of us get frustrated and like an extra little helping hand!

Perhaps things like Lvl 4 stones or maybe an occasional discounted item that usually costs a lot of coins
