I first noticed this coupon code when I got the "Graveyard Plots" short story collection by Bill Pronzini (
link) from Amazon a few weeks ago. I thought the coupon expired in February, but just got an e-mail which told me it was still good.
If you use the coupon code "LeapYear" at the Crossroad Press website (
http://store.crossroadpress.com) you can get $2.99 off any e-purchase, which can be an ebook or audiobook (they only have a couple, though). This means you can get a book for free (many titles are $2.99) or cheap.
The publisher is mostly focused on horror titles, though they are reprinting some authors moving their back catalog into digital media as well. Also, they publish novels based on the "Stargate" TV series if you like tie-ins. I got a Fritz Leiber story I had never read with mine.
Hope you enjoy.
