$750 after fees is $670 or so for the seller. Now if the seller searched 4-6 months for the shoe then it didn't fit him since he didn't get to try on first or bought them in the morning on a trip (with sales tax too) before his feet expanded then at $670 he is actually losing money.
Not sure where this ridiculous entitlement comes from. And chances are he doesn't know about styleforum neither. And if he lists here he would still need money to cover PayPal fee, shipping (an if he has no experience then 15-45 minute post office wait) and countless lowball offers. $750 is a pretty damn fair price for the seller. The seller shouldn't have to lose money so you can pay retail price on a pair of shoes. Should I go into leathersoul and demand them to sell me those new plaza boots for $400?
