Has anyone joined Penguin Random House's new
Rewards Program?
Looks like it might mainly be hardcovers and digital editions that are eligible (i.e. Nalini Singh's
Wolf Rain and
A Madness of Sunshine are eligible in both digital and hardcover, but
Archangel's War is only available in digital not mass market paperback). Audio looks to be eligible as well, for the few titles I saw with an audio option listed. And trade paperbacks also seem to be eligible.
You can buy the books at other retailers and submit your receipt.
Basically every book is 10 points and once you have 120 points (12 books) you get a code for a free book up to $30 value.
Points expire after 2 years. But as long as you buy at least 12 books over 2 years you get a free book. Since agency pricing doesn't allow other discounts every little but helps, even if only toward a new print book.
It looks like paperbacks are eligible to get with a redemption code, they just aren't eligible to get points towards the code. It also doesn't look like you can redeem the code towards digital books since their storefront in print only.
ETA: Unlike when the Harlequin My Rewards program started, books you purchased previously (before the date you joined the program) aren't eligible.
