Thanks Koala for bumping up this great offer that was buried in the forum! Using the link to save.ca listed below, you can order a free can of Purina Pro Plan cat food.  I received this some time ago, and was surprised that the offer is still valid, but it is! There is a limit of one coupon per household.

Time to make a nice tasty sandwich 😛
Thanks!
