I used the weekend insert BOGO coupon to get some of the Chef Michael's Dog Food bonus 2-paks at Petsmart. When you open up the cardboard wrapper, there is a coupon good for a FREE can of Chef Michael's dog food (up to 1.00), OR $1.00 towards any bag of Chef Michael's Dry Dog Kibble. The 2-pak is a "special BOGO package", same price as the single cans (reg .79, sale .50) ...... so, I would assume one can go back with that *free can* coupon, get another BOGO package with it, which would give you yet another coupon, etc etc etc.
