insane: The one just up the road from the Apollo center on Rosedale Road usually stocks some good stuff (leave me some :p ). Otherwise on occasion I've found the shop next to BurgerFuel, Subway, Caltex, Nandoes etc (next to the Albany Mega Center) to have some OK stuff at times too. 

A friend used to buy from the SA shop in Browns Bay, but I think the place may have changed owners a few times so I can't be certain they still do.
