Canadian Freebies: Palmolive Pure & Clear Detergent
I've never seen this website before, but it accepts Canadian details in the form (just select Canada in the drop down list).
If you are concerned about giving over your details to an unknown website, you'll have to make the decision on this one.
The website was only registered on the 6th of September 2009, and it is registered to an individual in Vancouver - more info here if you want it to help make your decision.
Thanks to Catherine.
