here if you want (found on Jill Caltado.com).
I've only copied and pasted a couple key highlights as the whole document is kinda long:
NOTE: Jewel-Osco and other retailers issue coupons such as printed ad media coupons that are manufacturer coupons and contain the words "redeemable only at their retailer (e.g. Dominick's, Walgreens) this type of coupon is redeemable at Jewel-Osco as long as the coupons states "Manufacturer Coupon".
Catalina checkout coupons printed at other retailers may be accepted for redemption following these guidelines:
Manufacturer: (e.g. coupons state "Manufacturer Coupons" and contain the words "redeemable only at their retailer (e.g. Dominick's, Walgreens)"
Competitor store coupon: (e.g. $.50 coupon for Dominick's brand 16oz loaf bread may be redeemed when a 16oz loaf of Jewel bread is purchased)
Buy 1 Get One Free and Cents off coupons. A customer may use a B1G1Free manufacturer coupon and a manufacturer cents off coupon on the one item that is being purchased as long as the coupons do not exceed the price of the item. (e.g. customer purchases 2 cans of Bush's Beans, they have a B1G1Free manufacturer coupons and present a $1 off coupon, as long as the price of the 2 cans of beans exceed a $1 both coupons may be redeemed).
