If you're in the Montreal area. I came across, what seems like, a closeout book store. It's located on the top floor of Plaza Cotes-Des-Neiges (where the supermarket used to be). All the way against the back left wall is a huge selection of amazing business reads. I've come across Godin, Peters and discovered many more ranging from $3.99 - $6.99 and they are brand new. But shhh, don't tell too many people. Last week they were running a "buy 3 get one 1 free" special.
Online, I've discovered another amazing place: www.bookcloseouts.com
- they are based in Canada, so you save on duty but they charge in US funds. Before you order from Amazon or Indigo, check it out - I've been pleasantly surprised to get something I was going to spend $30 on for $4.99.
