If you're not familiar with SavingStar, here's more information about it . . .
With SavingStar, you can save eCoupons to your grocery store loyalty cards and automatically get credited when you swipe your card at checkout. The savings doesn't come off at the register, it gets credited to your SavingStar account. You can request your payment via Paypal, bank deposit, or gift card when you reach $5.
They say new coupons appear on Thursdays, but the coupons don't change much. I often go, just to load what I have a chance of buying.
The Arizona stores that participate are Fry's, Bashas, CVS, and Albertsons. (Since we don't use loyalty cards at Albertsons in AZ, you will have to ask for one at customer service. It should be their "Upromise Keytag." I asked for this once and they had no clue what I was talking but, so your results may vary.)
They are not meant to be combined with paper coupons. In all honesty, I load them and forget them, so sometimes I end up with double savings. Here's their official statement on that:
SavingStar eCoupons will work whether or not you combine them with other services' coupons, but they are not intended to be used this way. Generally, manufacturers state that it is against their policies for shoppers to redeem more than one manufacturer's coupon for the same purchase. Using in-store coupons in combination with SavingStar eCoupons is not a problem. In the future, we may implement mechanisms to limit the combination of SavingStar eCoupons with other manufacturer coupons
