This week at CVS you get $5 ECBs if you buy $10 of participating Glade products. The twin-pack scented oil refills are on sale for $3.99. There was a coupon in the 11/2 Smartsource insert for buy a refill, get a warmer free. The warmers are not stated in the ad as being eligible for the ECBs, but I bought some, and they did give ECBs. So, buy a refill for $3.99 and a warmer for $7.99 (the fans and night lights work too.) This will bring your total above $10. Use the free warmer coupon and you'll only have to pay $3.99, but you'll get back $5 ECBs!
