How BuyBackWorld's service works

To begin, first lock in your trade-in price by visiting BuyBackWorld's website, where you will be asked to assess the physical and operational condition of your device. A few days after locking in your price quote, a pre-paid shipping box will show up on your doorstep. You'll then have 30 days before you need to pack the device securely in the box and drop it in the mail. Alternately, you can use your own shipping box and simply print and affix a pre-paid shipping label from BuyBackWorld's website during the price lock process.

Once your device passes inspection, BuyBackWorld will send payment within two business days. If your price quote changes for any reason upon inspection, you'll receive an email and if you're not 100% satisfied, they'll return it to you for free (BuyBackWorld is known to be gentle when inspecting trades, however). Also, if you choose to lock in a price quote today but change your mind about sending in your device, that's fine too. There's no binding obligation. Similarly, if you were to ever lock in a price-lock on a trade-in and have it expire before you can submit your device, you can simply lock in a new offer.

Why use a buyback service?

Using a buyback service as opposed to selling your device on eBay or Craigslist has its advantages. First, there are no upfront costs since shipping a phone or tablet to BuyBackWorld, a leader in the buyback space, is free. You'll also get 30 days to send in your trade-in. For those purchasing an iPhone 7, this means you'll likely be able to keep your current device until your new iPhone ships. Factor in the amount of time it takes to set up, administer and deal with buyers on eBay or Craiglist, and the simplicity of a buyback service is even more appealing.

However, not all buyback programs offer cash for used devices. Apple's iPhone Trade-up program, for example, gives customers a store credit or Apple Store gift card for trades. BuyBackWorld, on the other hand, offers higher cash payouts in the form of a check, PayPal deposit, direct deposit or prepaid debit card. That means you're free to use the money to buy an iPhone 7 or anything else instead of being tied to one store. At press time, readers can get a cash payout of up to $352.00 for an iPhone 6s Plus or up to $308.00 for an iPhone 6s. It's worth noting that those who elect to be paid via a BuyBackWorld.com gift card will receive a 5 percent bonus for an even larger payout.
