It's easy for the tech world to forget that not everyone is looking to buy a new $200 phone on contract every six months. Vodafone UK hasn't forgotten, though. The British carrier is launching a new service to help put top-tier smartphones in the hands of pay-as-you-go customers by selling them lightly used hardware. More specifically, phones exchanged within the carrier's 7-day return window.
If you're buying a phone without a contract, the up-front cost would be slightly cheaper, as one would expect from a used device.
