Walgreen Shopping: $1.09 (just tax)

I had read in a couple places that Oral-B Pro Health Clinical Toothbrushes were FREE at Walgreens this week!  They're on sale for 2/$7.  There is an advertised $4 Register Reward when you buy 2, but there is also a bonus $2 Register Reward printing as part of a national Catalina!  When you use 2 $.50/1 coupons found in the 10/28 P&G, you'll pay $6 and get back a $4 and a $2 Register Reward, making the net cost FREE!  I went to test this out, and here is what my transaction looked like:

Transactions 1 and 3:
2 Oral-B Pro Health Clinical Toothbrushes, 2/$2
Buy 2, Get a $4 RR and a $2 RR
Used 2 $.50/1 from the 10/28 PG
Subtotal: $6, Total: $6.52
"Paid with 5000 Bonus Rewards Points ($5) and $1.52 OOP
Got back $6 in RRs
Net Cost: $.52

Transaction 2:
8x10 Photo Collage, FREE (no longer avalable)
8x10 Photo Enlargement, FREE (still available!)
Tums Ultra Berry 3 Rolls/12 count each, $3
Buy 1, Get $3 RR
Subtotal: $3, Total: $3.05
"Paid" with $2 RR from Transactioin 1 and $1.05 OOP
