BENTONVILLE, Ark. -- The world's largest retailer is limiting U.S. ammunition sales to three boxes of shells per day, per customer.
Walmart said Thursday the restriction is in place because the supply of ammunition has become tight.
Ashley Hardie, a spokeswoman for the Bentonville-based company, says Walmart is monitoring its ability to meet demand and will lift the restrictions when it is able to.
The company doesn't break out sales of individual items and Hardie wouldn't say how much sales have increased. She says the limits apply to all types of ammunition and are in place to ensure as many customers as possible can be served.
Gun shops have reported increased sales since the massacre of 20 first-graders in Newtown, Conn., revived the nation's gun control debate.
