Campbell's Coupon + Possibly Free Soup

There is a new Campbell's Soup Printable coupon available here.  The coupon states save $0.50 on any two Campbell's condensed soups. (excludes Chicken Noodle--even though this one is pictured on the coupon??, Cream of Mushroom, and Tomato).  It does not exclude cream of chicken, or any other cream soup.  If your store doubles this could be a great deal, and possibly free when paired with a good sale.
