I visited a hair store today with 3 gacha machines each holding an assortment of hair that you could win. Above each machine was a display of the hair in that machine. Each machine had some secret prizes you could win too - probably different hair.
On the other side of the store is a wall of group gifts and freebies.
The store did have things for sale - you were wondering right? They were on the back wall - and i forgot to take a picture of them!
Notice the black walls. Lots of windows - the ceiling and the front wall. It was a small store in terms of floor space. All stores in SL seem to be tall so that there is no interference with the camera that hangs behind the avatar.
