I was just browsing Wargame Vault and noticed the US price of the PDF of W@W is USD29.95, same as the physical paper rulebook.
Switch to Sterling (and Mongoose are a British company I am led to believe!) and the GBP15.00 physical paper rulebook will cost you GBP21.81 as a PDF.
Not quite sure of the moral of the story (!) but either the US paper rulebook should be nearer USD20 or the UK paper rulebook nearer £22 if you use the WV exchange rate (which seems nearer that of the real world!)
