Idea VS scammers!!

so there is a lot of scammers, they make like few same itesm like heavy belt white for super cheap price and many ppl fast join to buy it..and they put like 5-10 belts for 1 ex and 1 for 1 PERFECT ex..and ppl who want to buy it faster then rest got scammed. so PLEASE can u make WARNING msg if u buy another item there will MSG LIKE U WANT TO BUY THIS ITEM FOR DIFFERENT PRICE OR mb u can make LOCK in ur stash FOR currency that cant be used for buy. or make ur OWN idea, but we need IT ASAP thx.

I think you should only be able to spend currency you have in your inventory, not what you got in your stash. That would solve this problem...
