I shop their clearance racks and find great deals on clothes for my daughter. It takes time and patience because of how things are organized ( or not so organized) but I don't mind.
The workers are usually preoccupied. Most times they speak when you come in the door and then you don't interact with them again until check out.
The aisles are super narrow so navigating a shopping cart, wheel chair or stroller is a bit challenging.
I've never sold to them so I don't have any info on that.
