Shelby American is adding a little incentive to pick up one of its one-off Ford Mustang creations: Buyers won’t have to pay shipping on the 2012 Shelby GT350 and the 2007-12 Shelby GT500 Super Snake--as long as they order by July 31. Depending on where a buyer lives, that could be a savings of up to $1,500.
