This is mildly interesting, although perhaps only to me!
Amazon.co.uk are taking baby steps towards making titles self-published on Amazon.com available on the .co.uk site too. Here's Sudoku Xtra 5, which has shown up quite quickly (other titles took months) and is actually shown as available from Amazon.co.uk directly (as opposed to a very expensive Marketplace seller).

Anyway, it's priced at £6.62 (which is its US Amazon.com list price of $9.99 converted to UK pounds) and is listed as taking 1-3 weeks to dispatch, which whilst not cheap is not insanely over-priced either, and who knows how long it will really take to come - Amazon do tend to pessimistically overstate delivery times so that you are pleased not disappointed when they arrive!
Edit: and I also see that my 25x25 Sudoku book is available for the same price but in just 2 days to dispatch:
