BENTONVILLE, Ark., Sept. 10, 2013 /PRNewswire/ -- Trading up to the newest smartphone just got easier and less expensive for the millions of smartphone users in the U.S. Starting Sept. 21, consumers will be able to receive immediate credit towards the purchase of a new smartphone when they trade in their current smartphone at more than 3,600 participating Walmart stores and Sam's Club locations nationwide. Walmart's trade-in program offers an immediate credit from $50 to $300 for more than 100 smartphones. Examples of trade-in values for working, non-damaged smartphones include: $300 for an Apple iPhone 5, $175 for a Samsung Galaxy SIII and $52 for a Samsung Galaxy S2. "Smartphones have become a part of our customers' everyday lives and as new devices launch more frequently, trade-in programs are becoming more popular," said Steve Bratspies, executive vice president of general merchandise for Walmart U.S. "More and more, customers are choosing where they purchase new smartphones based on where they'll get the best value for their trade-ins. Our goal is to give them more value for their old devices and the lowest price for their new one – all part of our promise to be the best destination for wireless." How It Works Customers should bring their working smartphone to an associate in the electronics department at participating Walmart stores and Sam's Club locations. In partnership with CExchange, the value of the smartphone will then be assessed by answering simple, unbiased questions on the device's condition and specifications. Once accepted, the trade-in value will be applied to a new smartphone of their choice – like the Apple iPhone 5 for $98 or the Samsung Galaxy S4 for $138 – with a two-year contract from AT&T, Verizon Wireless or Sprint. Walmart customers can also apply the trade-in value to smartphones available with prepaid plans like Straight Talk, which is only available at Walmart, which provides talk, text and data for $45 a month. Everyone Benefits – Mother Nature Too Walmart's smartphone trade-in program is consistent with the retailer's sustainability goals and will help customers and members recycle smartphones responsibly. According to CExchange's green policy, smartphones traded-in at Walmart and Sam's Club will be never be sent to landfills, domestically or internationally.
