Hello everyone, I am contemplating selling (in UK) a pair of Nike Mercurial Vapor II's in Flint Grey. They are in excellent used condition (with only light usage). I have seen Vapor II's reach decent values on eBay and understand this is quite a rare colourway. I am also contemplating selling to a boot dealer although they apparently typically insist on the seller providing an asking price. To help me decide when or if to sell, would anyone please be able to help me estimate their price on the current market? Thanks so much.
