I think it was a mistake on the tag, I found it really hard to believe that the jeans dropped from 210 to 40 bucks. I'll go out and check the prices. PM me all of the sizes u need. (It's more organized that way) I'll be heading out to the Rack tomorrow
here is the basic rule for current season stuff on ebay.
Most seller get the product for 50% off (most likely a hook up from an employee- or several- of a store, especially the ones who sell with retail tags.) They usually list them for ~25% off and profit ~25% gross on each pair.
