Ass hat that I am I completely forgot about this. These books are in a Kindle promotion until Friday, so you can get ’em cheap:
This covers both the US and the UK. Here I just spotted that Brass Man is available for 99 pence while I’ve been told that in the US the price is $1.55
Update
No, I’m wrong. Apparently I can buy it from Amazon.com for $1.55 but US citizens have to pay the full price. The deal obviously only applies to the UK.
