i used quick sell on a pair of boots (i think) and then i go into a battle and get same pair of boots ( maybe a different color ) later i find myself in the shopping district and i see i can sell some things in my bag. so i walk into the closest store and guess how much that pair of boots costed. more than they did in quick sell. is this a glitch or is it supposed to be that way. if it is supposed to be that way it isn't fair. people are using quick sell so the won't have to go to the commons area just to sell. they should get full price. which is another problem. however you sell you don't get back full price.
Quick sell never brought the same price that a shop or Bazaar can for selling things. Shops usually offer a lower buy price then the Bazaar. It all comes down to how handy you want things to be.
I sell everything I can at the Bazaar and then use shops to sell no auction items. Quick sell is a last resort for people whose back packs are full I guess. The only issue is quite a few wizards have accidentally sold everything using this and that included crown gear and water works gear. I think it's an option we could do with out really.
It's like selling to Prospector Zeke and selling at the Bazaar. It's more because it gets bought by wizards, while selling to default vendors gets abominated.
