Bargain @ $1.99 or less from Open Road Media, available in multiple stores (couponable @ Kobo):
Western Romance promotion, from old school backlist authors including Elizabeth Chadwick, Constance Bennett, Gwen Bristol, et al. Includes some which seem tilted more towards romantic historicals.
No idea how long this sale will last, but presumably good until the end of October since they put it up on their blog a couple of days ago.
