This week at CVS, The Fragrance Collection by Glade 3-wick candles and reed diffusers (great stocking stuffers!) are 6.99 and earn back the full 6.99 in ECBs. Go here to sign up and print a coupon for 2.00 off. You'll pay 4.99 + tax and earn back 6.99 in ECBs, which you can use on just about anything in the store. Or, if you have 6.99 in ECBs, purchase another $2 item and pay with the 6.99 ECB. You'll end up just paying tax for two items.
I bought a pack of Pampers (on sale for 9.99, used a 1.00/1) and a candle. I used a 3.00/1 from All You magazine, paid with a random assortment of ECBs and ended up paying around 1.04 I think out of pocket. Plus I got that 6.99 back.
Also, don't forget to scan your CVS card at the little coupon machines if your store has them. I got some really great coupons today, and remember that CVS permits you to use one CVS coupon AND one manufacturer's coupon per item for even greater savings.
