We have a two-tiered veterans discount policy. The discount is available to all veterans on major patriotic holidays including Veterans Day, Memorial Day and Independence Day. We're also one of only a few retailers that provides an everyday discount to active-duty, National Guard, Coast Guard and reservists, as well as retired (typically 20-plus years of service) and service-connected disabled service members, and their spouses.
