ST. LOUIS (KMOX) -- Three Schnucks stores are temporarily closed -- and the chain's 24 hour stores are reducing hours again. Stores in Shrewsbury, on Lemay Ferry in St. Louis County and a store in Alton are closed through Thursday at 6 a.m. -- when they reopen, they'll be open until 10 p.m. The grocer on Sunday announced stores would be closed at midnight to facilitate more cleaning and stocking -- but Monday further reduced the hours to 10. The one exception is Culinaria -- Schnucks' market in downtown St. Louis at 9th and Olive, which will cut back to a Monday through Friday 9 to 5 schedule. They'll be closed on weekends.© 2020 KMOX (Entercom). All rights reserved.
