Where can I buy an iPad?

Nowhere seems to be selling iPad. I just went to PC World and they don't have any in stock and when I asked them when they will get more back in they seemed very vague and said we get orders in every so often. LIKE THATS VERY HELPFUL??? On the Apple website it says shipping in 7-10 days and I live no where near an Apple store. It just seems so stupid that I can't even lay my hands on one. It's been 3 months since release you would have thought that supply would have caught up with demand by now...
