I’ve been traveling, so not sure how much longer this will last, but an omnibus of all fourteen books in Philip Kerr’s Bernie Gunther series is on sale for £2.99 (!!!) right now in the UK. That’s less than £0.25 each if you need them all, and it’s still a great deal if you only need a few. And it’s a great series, with several books awarded or finalists for various Edgar, Shamus, Dagger, etc. awards. In the interests of getting this posted quickly, I’m not going to list all the books, here’s a link to Kerr’s SYKM webpage. But it really truly is all of them!

Now back to its normal price of (gasp!) £44.99…
If you missed this earlier this year, it’s now on sale again, this time for £3.99, which is still a great price. The links in the OP are still good.
