Buying multiple copies of same item.

[Wumgum]

Many people oftentimes carry multiple weapons of the same category, the problem is that if you happen to have a prefered kind of attachment, like the extended magazine balanced or a specific scope, you can only use one at a time due to the fact that the game doesn't allow you to buy more then one copy of the same item. This restriction doesn't seem to make much sense and should be removed as it severely limits players in regards to their choise and the stuff they'd otherwise be willing to buy from your shop.
