This year, Ben and Jerrys ice-cream stores are having their free cone day on the 23rd of March 2010, from 12 to 8pm.
So write the date in your diary, and I shall bump up this post closer to the time.
Now, the problem is that there are only a few Ben and Jerrys in Canada, so this may not be available for everyone. There is a store in Ontario, one in British Columbia and a few in Quebec.
I'm a big Ben and Jerrys fan. I find their ice-cream quite expensive, so it's usually only bought as a treat. Cherry Garcia for the win!
