Have you paid attention to gift card deals at Target? They have them almost weekly. Often they're not such a great deal, like buy 2 boxes of diapers at $27 each and get a $5-$10 gift card. But occasionally they're pretty great.
This week they have a Kellogg's deal: Buy 5 boxes of Kellogg's cereal and get a $5 gift card. Most boxes (in my area) are priced $2.54 to $3.99. I got all this cereal (that's 10 boxes) for just $12.14 OOP PLUS I have another $5 gift card.
I split it into two transactions to maximize my savings. There are a few $1 manufacturers coupons out there or you can use a $1 printable here.
In the first transaction I got 5 boxes and used 5 $1 coupons. My total OOP was $8.54 plus I got the $5 GC. Then I got 5 more boxes and used 5 more $1 coupons PLUS that $5 GC, making this OOP only $3.60 and I got another $5 GC.
I try to take advantage of these Target deals whenever they come up. If you can use coupons and make it a good deal anyway, it's well worth it. I'm stocking up to do some major Christmas shopping!
