For Oldies but Newbies:
If you know a little about couponing already and have a binder full of coupons, then you can see how I did the Walgreens Trip from 3/1/11 in detail below. FYI - There are 5 transactions total. The coupon lingo for the total of your transaction is called a "scenario" So this is my "scenario", for my trip.
(1) Applied Nutrition Anti-Aging Total Body Defense, 50 ct. $10.00
