If you have the 2.25/1 Finish coupon from the 1/2 Smart Source insert, use it this week at Target. Target has Finish on sale this week for 2/5.00. Use the 2.25/1 coupon and pay only .25 per box (plus tax) I'm glad I have held onto mine for a while now.
Target charges the tax on the original price. Please note that they limit quantities at Target of 4 boxes. I wanted to get more, but they pointed to the sign that noted this. The cashier said that was my limit for the day (not the transaction)
