You might get a higher price if you sell your phone yourself on an auction or resale site. For example, I’ve seen the same iPhone 4S listed for as much as $424 on Amazon and $417 on my local Craigslist site.
There’s no guarantee, however, that you’ll get the price you want. No one may bid, or your auction might go for lower than you hoped. And most sites charge fees.
If you’re willing to take the risk, here are a few sites worth checking out:
eBay – Attracts millions of potential buyers but charges fees.
Amazon – You can set your own price, but you’ll pay listing and referral fees.
Bonanza – Works like Amazon, but smaller. I only saw a handful of iPhones for sale, but they charge a smaller selling fee.
Craigslist – Connects local sellers with local buyers. Free, but you’ll have to meet the buyer in person to close the sale.
