Sorry if this was already mentioned but I was at my new CVS today and they had a
2 pack of Ritz crackers for $6 or $5.99 (can't remember) with
2 ECB.
It even said the promotion on the box (buy this double pack and receive 2 ECB with your card). It goes on til 6/13. There is a $1 IP on coupons.com you could use.
