by Kerry Taylor (HarperCollins Canada, 2009).
I haven't read this book yet, but Leah McLaren gave it a plug in the Jun 6 2009 Globe & Mail (yes, in the dreaded Style section, which has only McLaren and the horoscopes to make it worth opening at all). Apparently, saving money is now stylish. For poor people, this means all those rich and formerly rich people have started competing with us for the most economical stuff. And that makes all the economical stuff go up in price faster than the expensive stuff. In 2007, the Canadian government admitted there was about a 2% cost of living increase; however, the price of the cheapest lunch on campus had risen from $4 to $5 - a 25% increase!
Anyway, here's a link to more about Taylor's book:
