This surprises me actually, that the stock is underperforming. My MK store is always jammed packed. The customers are not browsing they are buying. Belk Dept store just expanded their MK dept TWICE in the past year.
With Coach I think people did not want to pay full price because the full price styles went to the outlet in a couple months. But from what I understand, the bags at MK outlet are Made for Factory bags, not full price deletes. With MK I usually wait for Dept store sales but I also don't mind paying full price for a bag I think will sell out and it usually does
My boutique only ever has a few customers at most inside but the outlet has a lot (nothing compared to Coach outlet though). I don't typically buy anything at the outlet because the deletes I like are sold full price there! I can get better deals at dept stores!
