I had found a weapon upgrade for levelling up weapon. You must do the last upgrade and finish it at the same time you must level up too. I don't know if it working for iOS but it work for android. The normal upgrade price is still the same like the first level item unlocked(upgrade1/2/3)but you must start it from the first item unlocked. That all from me. Sorry if it have some mistake in writing.
