You can bring a friend (or two) and they can buy one also. I'm in San Diego and last time I drove back from Northern California I just stopped by (it's in Tustin) with my wife and picked up 2. If you need many then of course it doesn't work. I don't think there is any rule about you going back in another day either, although I guess if you went everyday they might notice. They didn't take down any information when I bought them, they just handed them to me.
