After the problems with paypal not accepting my credit card last night, Im back at home in the UK and after much contemplation I went ahead and purchased 2 copies.
Currently saving $40 per copy, plus when they have to charge VAT, next year I would presume, that would add an extra $28 (20%) onto each copy, so buying now ive saved $136. Plus if I dont want/use them I can flog them on in 3 months for what I paid!
