Concur with it being very difficult to find...
It's not directly opposite Bunnings. When you turn into Bremner road, go straight ahead at the roundabout and its in the set of shops after that on the right. A couple of doors down from the adult shop, which as a big sign...Unlike Skyshop. The only sign is on the door.
Its cheaper than other places BUT don't expect good service from Mr Grumpy in there though. You have been warned!
