Subway has a large number of stores in local markets. Most likely, there is a Subway store in your area. Some Internet surfers have had luck finding Subway coupons by checking the Subway restaurant locator at Subway.com, then searching the individual store web sites in their area for local coupon deals.
Finding Subway coupons in this way is a long shot because most stores don’t seem to have their own web sites. It might be worth a try if you really enjoy Subways and are desperate.
