Well, I am a Ralphs shopper but sadly that might be changing soon.  In their most current grocery ad there is an extra insert talking about changes coming.  Here are a few of them:

**They will not longer be doubling coupons :(((((
**Rather than earning rewards points that will then be converted to money you will now only be able to use your points at either a Ralphs gas station or at Shell stations.

These changes will start taking place April 1st.
