Try SavingStar!

SavingStar is a site that allows you to "double dip" on the coupons you may already be using.  You can either use their website or even get their downloadable app on your phone.  It allows you to select money back on items that normally already have coupons associated with them and when the balance reaches $5 you can request the money via paypal.  So its not getting it back right away, but it is a good savings anyhow.  For example, this week we needed some sandwich bags and I had 2 $1/1 Glad sandwich bag coupons that I printed online.  SavingStar had a deal if I bought 2 Glad sandwich bags that they put $1 in my SavingStar account.  This week they happened to be on sale at 2 for $5 so after my coupons and the saving star benefit it was like paying only $1/box!  Give it a try at www.savingstar.com  Remember that they way they know you purchased the item(s) is buy using a registered savers card from CVS, Jewel, Pick N Save, etc...
