On Simplyaudiobooks Canada, they are holding 25 days of Christmas deals for your viewing pleasure! Each day will be a different offer, so there could be something good for Christmas gift giving.
As I post this, I realize I have missed the first few days, as they are now on to day 4. If you manage to get today's deal, you can download a free book, A Child's Christmas!
Tomorrow they are reported to be offering a 25% discount off The Wheel of Time series. That is an excellent series, I think I have read them up to book 11.
Click through each day if you want to know what offers will be available!
