I thought I would let you know that I used my first 2 Cellfire coupons yesterday.  I signed up Here, then chose the coupons I was interested in, inputted my grocery store reward card information and that was it.  When I got home both coupons showed up on my receipt with the word Cellfire and then amount taken off.  What I like even more is that you can double them up with a printable coupon.  My son loves Toaster Strudels and I had a coupon I printed from the internet.  I used it  and also got credit for the Cellfire coupon, doubling the savings.  They are always changing coupons, so even if you do not see anything of interest now, sign up and bookmark the page and then check back each week when you are planning your grocery list.
