I have been trying to buy Geomag Pro in the UK with not much success. The number of sets (of the original Geomag) appearing in Ebay is getting less.
Geomag World want me to pay with a bankers order.
Amazon UK have followed their American parent and does not sell Geomag Pro. There is an extreme lack of imagination - the decision makers can only think of Geomag as a children's toy and not as an intellectually stimulating construction set.
However other branches of Amazon are not quite so squeamish, and I found that Amazon France sells Geomag Pro - and accepts payments online (http://www.amazon.fr). You have to pay in euros. And it helps to be able to read French.
The bonus is that your UK Amazon username and password works.
Unless other retailers start stocking Geomag Pro the product will die.
