Flemington Outlets

Went to the Flemington outlets in NJ this weekend, got some work clothes from CK. As we were leaving we witnessed a strange sight. A family of 5 in an older corolla parked next to us, and proceeded to pull 4 bags filled to the brim with clothes. The left the other 5 bags in their overpacked trunk, and went towards the outlets. Peculiar, Don't you normally have bags to carry when you leave not when you arrive. I suspect something is a foot. Not one of the bags was from a place even in the outlet complex. What were they doing? Scamming? But how? Do they go to a consignment shop find clothes for really cheap that still have the tags and return them to the store for credit or cash?
