Post Cereal for Cheap at Albertson's

I just found this deal on Money Saving Mom. We like hearty cereals for breakfast, so I'm always looking for deals like these.

"Through September 6, 2009, when you buy 4 Post Selects at Albertson's, you'll get a catalina good for $3 off your next order. Here's how you can get Post Selects for only $0.25 per box:
Buy 4 Post Selects at $2.50 each
Use 2 $1/2 coupons from the 8/8 SmartSource insert
Save $4 instantly
Spend $4 plus tax out of pocket
Get back a $3 catalina
$0.25 per box after the instant discount, coupons, and catalina

Note: If you don't have these coupons, the boxes of cereal are still only $0.75 per box after the instant discount and catalina. Plus, you can roll this deal using the catalina earned from one transaction to purchase four more boxes. And so on."
