Yoplait Yogurt Score

QFC is having a sale through TOMORROW (Sunday, Jan. 23) on Yoplait Yogurt.  It is 3/$1 which is a pretty good deal as it is, BUT you can stack the sale price with coupons and a catalina that prints when you get 12.  Here is what I did:

Transaction #1
   12 Yoplait Yogurts @ 3/$1 = $4
   -$1/1 from 1/2 SS or you can use 2-$0.50/4 from here (or you could use 3 of these and get an even better deal!)
   FINAL OOP  $3

Get a catalina for $1.25 when you get 12

Transaction #2
   12 Yoplait Yogurts @ 3/$1 = $4

   -$1/1 from 1/2 SS or you can use 2-$0.50/4 from here

   -$1.25 catalina from Transaction #1

   FINAL OOP  $1.75

Get another catalina for $1.25

Transaction #3

   12 Yoplait Yogurts @ 3/$1 = $4

   -$1/1 from 1/2 SS or you can use 2-$0.50/4 from here

   -$1.25 catalina from Transaction #3

   FINAL OOP  $1.75

Get ANOTHER catalina for $1.25

SO total OOP was $6.50 making each yogurt $0.18!  If you count the last catalina towards this total making it actually only $5.25 that you are going to pay in the end (after you spend the catalina elsewhere) then the yogurt was only $0.15 each!!  This deal saves you $20.50!!
