WinCo does not update its offered coupons on a weekly basis. The coupons available on the site as of July 14, 2015, are due to expire on August 7, 2015, which suggests a monthly turnover.
If a WinCo customer chooses not to wait for the company to update its selection of coupons, large discount sites, such as Retailmenot, often offer deals. These deals may be one-time-only, expired or limited to a particular location, however, so they may not always work. WinCo does not accept rivals' coupons, but does accept generic manufacturer's coupons as long as they scan, are being used on the correct item (including size) and do not exceed $5 in value.
