When Ryan Mathre of Stillwater wanted to sell his iPhone 4, he didn't have time to post it on Craigslist or eBay. As a busy parent of two toddlers, he used an online reseller instead.
"I sold it for $160 on Gazelle," he said. "It nearly paid for the iPhone 5, and the whole online process took five minutes."
Gadget sellers like Mathre have a growing number of options to unload smartphones, MP3 players, laptops and tablets. Sellers are going beyond eBay to nearly a dozen online sites such as Gazelle.com that specialize in buying electronic castoffs. Other consumers are selling locally to pawnshops and, most recently, automated kiosks in malls.
While cellphones and MP3 players have had a modest resale market for more than a decade, the smartphone is what's creating a sudden surge of interest, said Dan Brauser, president of uSell, the Kayak of consumer electronics resellers.
More than 70 percent of Americans are expected to own a smartphone this year, according to a Nielsen survey. "The higher penetration and the much higher value is what's driving the resale market," Brauser said.
Not only are more Americans connecting to smartphones, they're switching to a new device every 18 months instead of two years.
Online buyers such as Gazelle, Buybackworld, NextWorth and BuyMyTronics are attracting the bulk of attention. They provide quick online estimates after a buyer completes a few questions about model and condition. If the buyer wants to sell, most companies send a box with prepaid postage for mailing the item.
But local options such as New Uses in Minnetonka and Pawn America also are seeing an influx of sellers.
