the fact that the dollar is rising doesnt change the fact that all of the other store's prices are region-based. I just noticed that you british people spend a lot more of your money than us americans do on GP32s... if the exchange rates were used to convert the amount Americans pay for FLUs and the amount British people pay it would be $150 dollars (80 pounds) via Play asia for 1 non-FLU to america and $167 dollars (90 pounds) via GBAX for one to great britain, or $210 (112 pounds) via Lik-Sang for one FLU to America and $232 dollars (125 pounds) via GBAX for one to Great britain.
The point is that it's considered acceptable across britain to pay a little more than it is for americans, the fact that the dollar is rising hasnt really changed any of the prices at any of the non-worldbank sites yet. Us americans view the converted prices at GBAX as way to high, wheras the British peoples view it as perfectly acceptable.
