This is exactly my point about it being a bad move for the designers. I understand that the motive is to get your name out there and recognized, but do you want to be recognized for something that is bad quality? Another poster pointed out that the people who already buy the more expensive versions probably won't buy these, so they're trying to hit another market. So, a person who is not familiar with the brand name buys a Target bag, and it's not made that well. What's their opinion of the brand name going to be? Say they walk into Macy's or Nordstrom's and see the a bag by the same designer. They'll pick it up, say "I saw this at Target, but it wasn't anywhere near this much! This is crazy!", and they'll put it down. They may not notice the superiority of the higher priced bag.
