Jewel-Osco currently has Post cereals on sale 2 for $3. In addition, they are also running the Post catalina deal that Albertson's is (Buy 5 boxes of Post cereal, Get a $5 catalina coupon off your next shopping order. Good through April 19, 2009.)
Combining these two deals with coupons can net you free Post cereal this week. Here's how:
Buy five boxes of Post cereal
Use two $1/2 coupons from the 3/29 SmartSource insert
Use one $0.55/1 coupon from the 3/1 insert (or, use 5 $0.55/1 coupons–if you have that many)
Pay $4.95 out of pocket
Get a $5 catalina back
If you have more coupons, you can repeat this deal and use the catalina you earned on your last order to pay for your next order making your out-of-pocket expense $0. Stock up!
And even if you don't have a lot of coupons, the cereal would still be only $0.50/box for every five boxes you buy after the sale and catalina–which is a great deal!
