Reader Trips - I am back in the Walgreens Game

It happened. I roped myself into a commitment with Walgreens again. It's OK though, most of this is going to our church.

12 Transactions, started with ZERO Register Rewards.
The first picture is the orders divided up by transaction, if you notice there are $.15 candies with almost all of them and depending on how many RR from the previous transaction I used on the next one depended on how many of those candy "fillers" I needed.... so here is the break down:

6 Gain Laundry - $5

-$2/1 9/11 SS

or - $1/1 9/11SS

12 Gain Dish soap - $1.67
-$.50/1 8/14 RP

(somehow When you buy 1 laundry and 2 dish you get two $3RRs)

6 Crest - $1.99 get $1RR
-$1/1 8/28 PG

6 Colgate Sensitive - $4.99 get $3RR
-$1/1 9/11 SS

2 Colgate Optic - $3.99 get $2RR
-$1.50 9/11 SS

6 Airwick Fresh Kits - $7.99 get $3RR
-$4/1 8/11 SS

4 Skittles - $1

-$1/2 in-ad and $1/2 HERE

and a bajillion pieces of candy

Total Spent OOP - $33.06

Total Saved - $161.73

Still have - $15RR... which leads me to believe I should have used $6RR in the second transaction but I seem to have forgotten to do that.
