I think you hit the wrong currency mate :(

Even if you had chosen the correct currency, quickbuyers are not adequate evidence to change a price. The entire point is to resell them for more. You need sellers at your suggested price, not just buyers.

Please take a closer look at the site rules before making your next suggestion; http://backpack.tf/vote?showrules=1

First: You put Refined instead of Keys

Second: These links are people buying Quicksells, that means they will sell for high price.

Close your suggestion, find more good proof and Open a new one with better currency.
