You know those shops which gives people an opportunity to sell things, and they provide space in a cube. Typically they sell HP accessories and toys there. Whenever you walk into these type of shops, what would you buy?
Well, I think that it is a bit different here in the U.S. I have only seen stores like you describe above set up for people selling used and antique items from rented spaces. Occasionally, you will see new products like toys, electronics, etc., but most of the space is taken up by the older stuff. When the wife and I go to such places it is typically not with a specific purchase in mind, but more the opportunity to see a wide array of unique things that could be purchased, if desired.
When I walk into a COMPARTMENT shop, I would be expecting to buy COMPARTMENTS just like if I walk into a TOY shop I would be expecting to buy TOYS.
