Doesn't it follow that, with the exchange rate being what it is.... well think of it this way.
I'm in the US... if I wanted to order something from the UK, I'd have to pay a LOT more than the equivalent price here. So... with the pound worth so much more these days, doesn't it follow that you could buy things a lot cheaper if you ordered them from the US?
I imagine you could pick up a DS from here in the states with shipping and all for very cheap, if this logic holds true. And just because many of the major retailers are sold out of the thing, don't think they're all that hard to come across....
