In the UK from 1st January 2015 the VAT rate on Amazon's Kindle books will rise from 3% to 20%. Basically the VAT rate charged is changing from the VAT rate at the seller's location to the VAT rate at the buyers location.
I wouldn't mind so much paying 20% VAT on ebooks except that print books have a VAT rate of 0%! That winds me up no end.
While I can't justify spending hundreds of pounds to buy every book on my to read list before 1st January 2015 I think I'll be spending as much as possible.
