Well, my email box is full this morning with price drop alerts from EReaderIQ.
I've had price alerts set for quite some time for some of my favorite mystery authors, including Ross Thomas, Stuart Kaminsky, Carl Hiaasen,and James W. Hall.
A large selection is available today only, offered from publisher Open Road Media, and available in most of the stores.
For Ross Thomas & Stuart Kaminsky, I think this includes their entire catalog, and all seem to be priced at $1.99-- a great reduction from the normal $7.99 price.
The available titles from Hall & Hiaasen are their early works, about 3 from each.
There goes my book budget-- I'm pretty sure I'll be buying the entire Ross Thomas catalog, and a large pile of the others.
It's impossible to link to all, so here's the Open Road front page, with details. The page says "up to 80% off", and indeed most of the prices I checked are 80% reductions. Open Road publishes a lot of older material from excellent authors, and their website enables searching/browsing by genre and author. If you've got back-catalog stuff you've been wanting, it's definitely worth a look. If you discover one of your favorite authors with back catalogs offered here, perhaps you could list them. (I do see a Sayers thread that's part of the same special.)
