X-link to the Kobo Discounts thread for a weekend sale:
Through December 4th in Canada, the US, and UK, Kobo are promoting “Chilly Thrillers” under £2.99/$4.99, with selected titles in dedicated Horror categories and several strays filed in others. Genre authors I recognized include Graham Masterson and Christopher Golden. Many of these are probably publisher promos available in the other stores as well.
