when albertsons bought sainsbury's american supermarket assets in 2004, including star markets, star and osco were reunited under one corporate umbrella. by 2005, the signs on the front of all of albertsons-owned grocery stores with in-store pharmacies were changed, adding either "osco" or "sav-on" to the stores' logos, to emphasize the one-stop shopping available inside. the drug store name chosen reflected which of albertsons' drug chains operated in the specific marketing area. because new england had previously been an osco market area, the shaws and star market stores with pharmacies were renamed "shaws-osco" and "star-osco". as of january 2018, osco pharmacy has 55 locations within shaws and star market stores.
