Harlequin's new digital-first publishing house launched their first titles this morning. Until July 5th (at 8:59 EDT) they are having a 20% off sale on all titles in their new store.
Carina titles are being sold DRM Free in ePub and PDF formats through their store. They will also be selling through Amazon, Books on Board, Fictionwise and others.
Books are priced by length (word count).
EDIT: Some of the titles they're offering are pre-orders. Just thought I'd mention it as I didn't notice at first when I was poking around (look for the on sale date).
