I stopped at CVS today and earned $3.00 ECBs by only paying $.56 tax. Now that's a nice return on your money.
If you'd like to make a few bucks (Extra Care Bucks, that is), here's how I did it.
Buy 2 Glade Sense & Spray - $5.00 each
Use 2 $4.00 off coupons from 8/23 SmartSource insert
Use 2 $1.00 off Glade coupons from previous CVS receipts
Out-of-Pocket: $0 + tax
ECBs Earned: $3.00
