Used books on Amazon

I have bought quite a few used books from Amazon in recent times. They've all been titles I haven't been able to get locally. While they haven't been cheap, they've been cheaper than the corresponding Kindle titles. The other redemption here is that I got some bonus Amazon pay points for using earlier Amazon coupons. So I didn't spend much of my own money

Nul Points by Tim Moore
Do not pass Go by Tim Moore

I have read French Revolutions by Tim Moore before and loved it. Am hoping these are fun reads too.
