They are not making an average of two bucks on their kicks I guarantee you that. Look at their prices:
Yeezy 350 V2 - $650, MSRP $220
'16 Banned 1s - $285, MSRP $160
Chicago 1s - $285, MSRP $160
OG SBB - $385, MSRP $160
Yeezy 750 Choc Brown - $980, MSRP $350
Adidas NMD Pharell - $425, MSRP $220
Yeezy 750 GG - $900, MSRP $350
Yeezy 350 PB - $800, MSRP i think its $200 or $220
Yeezy 350 infant TD & PB - $350
etc etc
They're making well over 50-100%+ progit margin on these pairs and profiting big time since they move volume. If they've sold 100 pairs of RSBB's, who's to say they don't move that much volume on the above kicks I listed? That's a ton of profit, allowing them to absorb any kind of perceived loss on pairs they price for $200 such as the RSBB or Black Toes for $220.
IMO, as a volume reseller it is more beneficial moving large quantity at lower prices than sitting on inventory for months while pricing your shoes at "market."
