If you don't already shop at Walgreens and use their Register Rewards program, the week of 3/28/10 would be a great week to start! Many items are free after register rewards(FARR). I have some beginner scenarios lined out:
Dentek Floss 2.00(-$1IP)=1.00
pay $1.00+tax, get 2RR
Dove Haircare 4.00(-$2IP)=2.00
1 Easter tumbler (-in ad ivc) 0.13
use 2RR from trans 1, pay 0.13+tax, get 4RR
In my city, that's $1.65 including tax for floss & shampoo, get back that 4RR...profit of 2.35.
