eHarlequin.com is having an ebook sales as part of their 12 Days of Christmas. All ebooks are 50% off LIST price (not 50% off whatever the sale price might already be, but still a good deal).
Use coupon code HALFEBOOKS once you have your cart filled up. The coupon is only good today (Dec 2) and I suspect can only be used once, so add all the books to your cart at one time before checking out. Also, nearly every book I've ordered from eHarlequin.com has had DRM, so you won't be able to read these on a Kindle, but the EPUB format should work fine on most other ebook readers (the Mobi and PDF, of course, work fine on a PC).
