Save some money???

Ok so I've recently become a coupon dork. I used to think I was money savy,but now I really am. I am a faithful user of grocery smarts (great free site-leave comment for more info) and am saving tons of money. But not only do I use this site, but I'm reading several money saving blogs. Last night I was reading one ( http://www.beingfrugalisfabulous.com/), and found another great site for digital coupons. What are digital coupons?? You go on a website and register your Smiths/Vons card and the website saves to your store card coupons. There is no work in redeeming the coupons. I now have 3 sites that I use for digital coupons (http://www.cellfire.com/affiliate/fullpage.php?cf_tlc=cxr, http://www.pgesaver.com/Sites/PG_eSAVER/Page/HomePage, http://shortcuts.com/). When I use these coupons, it's like a fun surprise at the register, because I often forget which digital coupons I have. Even better, you can use a manufacturer coupon and a digital coupon! Happy savings!!!
