In general, Ralphs doubles coupons up to $1 (one like coupon per transaction). That means coupons for $0.50 or less will be doubled in value, but coupons for $0.51 through $0.99 off will only “double” to the price of the item or $1, whichever is less. For example, a coupon for $0.40 off will be doubled to $0.80 off. But a coupon for $0.75 off will only “double” to $1 off.
As of April 1, 2012, Ralphs only accepts coupons at face value (i.e., no more doubles).

You can load electronic coupons to your Ralphs Rewards card at these sites: Cellfire.com, SavingStar, Softcoin, Shortcuts.com and Upromise. Electronic coupons generally cannot be stacked with paper coupons at Ralphs.
