Go to Smart Source to print a coupon for Buy one VELVEETA Shells & Cheese Cup and get one free up to $1.30. You should be able to print 2.
These are also on a catalina deal at Kroger (in my area known as Hilander).
Buy 2 get $0.50 off your next order coupon at checkout.
Buy 3 get $1.00 off your next order coupon at checkout.
Buy 4 get $1.50 off your next order coupon at checkout.
Buy 4 Velveeta Shells and Cheese @$1.30 ea (probably less but this is the max price) = $5.20
Use 2 B1G1F coupons = -$2.60
Toal: $2.60 - $1.50 cat = $1.10 for 4 cups (or $0.28/ea) after coupons and $1.50 cat!! (this may be less depending on the price of the cups in your store)
