$.75 Post Cereal at Schnucks

Schnucks has select Post cereal on sale for 5/$10.  You can get them for $.75 using the scenario below until Sunday. I was able to do this myself today so I know this deal works. 

Buy 4 boxes of select Post cereal on sale for $10/5
use 2 of the $1/2 coupon in the 11/6 SS
there is also a $1.50 off 1 Marshmallow Pebbles in the Nov. All You magazine
Your total will come to $6 and then you will get a $3 catalina which makes the 4 boxes $.75 each

but then...repeat this transaction with 4 more boxes and roll over the catalina and you OOP will be $3.  You can roll this catalina over as many times as you want or for as many coupons as you have.
