You can see all the clubs before you buy them, the vendors are infront of each Club.
Hg visitors can also buy a Club but they need to buy first the grid money before you can buy Clubs. You can do that by the cash atm at the same region.
I was there to have a look whether I like to buy a club. I was not there so steal something. But was curious and clicked on a NPC to see what kind it is. AT ONCE I was kicked. Thank you for nothing, that's not how customers should be treated. I hope you built your clubs yourself and didn't steal them somewhere, otherwise you have to kick yourself from opensim.
