I don't get that post about SX sell back.....People who hit and don't want them just sell on SX now; what's the point? Nike doesn't need to flood the market, just ramp up until they find the right balance. We've seen them swing in both directions over the past decade. It's hard to find the right supply/demand balance, esp with black swan events like covid, supply chain issues, Fed money printing, The Last Dance, etc. Not sure why they don't like pre-orders, but they hype that results in resale certainly does help them.
I'm dabbling with Tradeblock for the first time as an alternative. Not sure how well it works...how long do people take to respond? Esp when I'm sending an offer with a shoe(s) they have on their wish list that basically matches current market value of both shoes, and I see they've been active minutes ago to see the offer. Get the feeling people aren't looking for fair trades, but looking to "win". Oh well.
