Old Navy is offering a Free Backpack with any $50 or more purchase on Sunday, August 5, 2012. This is valid in-store only and includes special savings on school supplies at Staples (and OfficeMax in the US). The image above states it is valid in the US only, but this is valid in Canada too, I got an ad for this in-store yesterday!
Offer valid while supplies last, supplies are limited, so come early. Limit one gift per customer.
