i know some luxury brands are wary of the secondary market out of concerns for brand dilution and the notion that the perceived value of the brand will go down if purchased under less luxurious circumstances. but that would not seem to apply to the secondary market for hermes bags, where used kellys and birkins can sell for 80 - 90% of their current "new" cost (assuming excellent condition). i find this if anything brand enhancing. is it simply that they don't want to play into the reseller mark-up market? because i just cannot think of any reason hermes would be unhappy to hear that someone purchased a 2004 birkin for $7000. and not making people feel welcome to have such purchases authenticated at the stores plays right into the hands of the counterfeiters. any insight?
