Kroger: Crayola Catalina + Deal Scenario!

Kroger has an awesome deal on school supplies.  When you buy $10 worth of Crayola products (other brands included) you will receive $2 on your next order.  When you buy $20 worth you will receive $4 OYNO.  This offer is valid thru 8/21. The best part about this is the catalina prints based on the shelf price instead of the sale price.  Here are two deal scenario's:

Buy 9 Boxes of Crayola Crayons = $20.25 (shelf price)
                                                   = $2.25 (sale price)
Pay $2.25 and Get $4 OYNO
Final Cost = 9 FREE Boxes + $1.75 MM

Buy 5 Boxes of Crayola Markers = $20.95 (shelf price)
                                                   = $5.00 (sale price)
Pay $5 and Get $4 OYNO
Final Cost = $0.25 each

The best part about this is these catalina's roll.  Which means you can buy the same products again, use the catalina you just received when you bought them last time and another catalina will print.
