Associated Press/Brynn Anderson A mass shooting that killed 17 people at a Florida high school has spurred a growing number of calls for companies to cut ties with the National Rifle Association (NRA). A number of retailers still offer perks to NRA members. These discounts help retain NRA members, according to Boycott NRA Partners. On February 14, gunman Nikolas Cruz allegedly killed 17 people at Marjory Stoneman Douglas High School in Parkland, Florida.
