That announcement brings down the curtain on what was meant to be the first phase of Quotient's plan to launch a major new competitor to Catalina's long-lasting checkout coupon program. Albertsons had been one of Catalina's largest retail customers, with coupon-printing machines installed alongside checkouts at more than 2,000 Albertsons, Safeway, ACME, Jewel-Osco, Shaw's and other Albertsons-owned stores, printing out coupons tailored to shoppers' purchase history.
