Keep Your Prices Reasonable
The game is too competitive to be charging outrageous prices. Sure, you can get top dollar for those Yeezy IIs and a few limited releases here and there but let's get real. There are more people buying sneakers now than ever before and there are more being made than ever before also. Keep your prices reasonable and you'll have repeat customers who are willing to pay your asking price on a regular basis. Make that loot on volume, not gouging.
