you keep revealing the highly coveted items for scams and you release them in the shop, so that it can lower in value, at the same time, retire a diamond shop item so it can gain value. like say if like if the legendary gloves retired from the diamond shop thier value would go up, and they put in an RIM such as Rare wings, for about 3 diamonds, the value of those would go down, how ever the value another item goes up.
