Sign ups would be done in advance on the Aasgaard Company website. That should be available in a in the next two to three weeks, depending upon when I get all the contracts back and to allow the Aasgaard Staff to set things up. The vagaries of exchange rates are going to be part of the deal. When you pay via credit card on the website, currency exchange is taken care of by the processor. You would pay in GBP, the Aasgaard Company gets USD. Since exchange rates are subject to unpredictable variation, I don't know that anyone would be able to predict when the best time to buy would be. Payment will have to be in advance. Anything else would be a potential disaster. Further, I don't want to be carrying a backpack full of cash around Europe.
