i do believe it is the consumer's job to be informed. you can't just believe that what a store/online retailer says they are - if so, IOffer, other fake sites (albeit illegal), would be getting much more business if people didn't do their research first.
it really is a retailer's job to make as money as they can, the consumer's job to be informed.
Gilt doesn't always have the best sales - i bought my mom a L.A.M.B. bag for $80 and my sister a L.A.M.B. cosmetic bag for $50 - a month later since they didn't sell that well they were $40 and $20, respectively. but that was MY fault for not waiting. oh well, i still like to look at their stuff, since sometimes i miss it in store
