This week at Target you can get a $5 gift card when you buy any 5 boxes of Kellogg's cereal.
The cereal is on sale for $2.75 each.
When you use $1/1 coupon here they are $1.75 each
If you can get access to several computers and print 5 coupons this could be a good deal.
Total would be $8.75 for 5 boxes plus the $5 gift card
It would be like paying $3.75 for 5 boxes or $.75 each.
