Cereal Deal at Walgreens

Not reading the fine print carefully can end up costing you money. Since I started couponing I save about 60% off our grocery budget. Couponing is a learned talent and sometimes you are bound to make mistakes. I made a big mistake and it may end up costing me $10. It is driving me crazy but I am trying to cut myself some slack. After all, I still got the items for cheap, just not as cheap as I could have. Plus, it is stuff we will use and in the past I would have paid full price for it. In the end these are the 2 lessons I learned:
1. Read the fine print carefully
2. If you mess up, count it as a learning opportunity.

So here is the deal so you can do it RIGHT:
In the paper last week there were Kellogg's coupons and a $10 rebate by mail. You have to do the deal between 8/5-9/30. I messed up and did the deal too early.
Go to Walgreens who is having a sale this week.
Buy 10 participating Kelloggs products get $10 RR
Kelloggs products are on sale for 4/$10
Use 5 kelloggs coupons=
$22 for 10 cereals/cereal bars
-$10 RR
-$10 Rebate=
10 for $2
