Okay this is what I saw happen while shopping on canal street. The stores had lots of very bad knock-offs on display. While walking down the street, every couple of feet someone would quietly mention brand names like "Coach, Gucci, Prada". If the person they were approaching showed interest, they would be told to follow them. They would take them to a store on a less busy street. They would go to the back of the store where there was a hidden door that led to a basement with several locked rooms. On Saturday, when it was super busy, some of the people on the streets would actually show you pictures of the bags they had available. I can't vouch for the quality of the bags from the hidden stock, but I can tell you that all of the bags that were visible from the street were very obviously bad knock-offs.
