This week at Walgreens you can get Excedrin for free!
Here's how you do it:
2 Excedrin Migraine: $1.99 each
2 Excedrin PM: $1.99 each
2 printable Excedrin Migraine coupons (found here)
2 manufacturers Excedrin PM coupons (from the newspaper)
Find 4 of the cheapest items you can in the store to make up for the $0.01 (check the clearance). Do 4 separate transactions and with each you will get a $1 Register Reward! If you do them all at once you will only get 1 RR.
So basically you are paying the tax and whatever extra things you buy to make up for the $0.01. and then you are getting $4 back! I messed mine up...I only did 2 transactions but I paid $0.75 for 4 Excedrins and got $2.00 back!
