I assume it may have something to do with a persons Locale as well. If its a consistent thirsty for Retro J area , resale will stay high.
In Pittsburgh though, once it gets close to that 1 month period where theyre un-returnable to a store alot of resellers panic ,and just want to get a profit ,so theyll let them go at semi reasonable prices. Thats how u play it.
Ftr when I say trade bait Im usually trading straight up ,no cash added via either end, unless market value demands it. Either way Im never above $50 ,that includes value of the trade.(i.e. if a pair I have is valued at 160 and the pair a seller has is at 170, Im not giving them anything other than the shoes for their shoes,but if mines worth 160 and theres retail was 200 ,Id pay them half the retail difference.
