Walmart cashes checks at its MoneyCenter from 8 a.m. to 8 p.m. Monday through Saturday, and from 10 a.m. to 6 p.m. on Sundays. These hours apply to check cashing and other money services at Walmart's MoneyCenter. Even if a store does not have a dedicated MoneyCenter, check cashing services are often available at the customer service desk during these hours. It is recommended to call the local Walmart to confirm specific MoneyCenter hours as they may vary by location.
