As the world drowns in second-hand smartphones, eBay is launching a new service for selling the devices that removes the hassle of having to create your own auction listing. The feature, called Quick Sale, is powered by eBay Valet, which will take photos of the phone, write the description, and deal with the payments and shipping.

You can get a quote for your old device on the Quick Sale website. The price is based on the type of phone, network, accessories, and the all-important condition (assuming it's not brand new). If you're happy with the offer, you can print out a shipping label to send your device to eBay Valet and, as long as it's as described, you'll receive the money before it's sold.

An interesting element of the Quick Sale feature is that it will show you the trending price of the smartphone on the main eBay site, along with a separate option that lets you list the item yourself in the traditional way. When using an unlocked Samsung Galaxy S7 Edge with 32GB, all accessories, and in excellent condition as an example, I was offered $239 using Quick Sale, whereas the trending price was $511.

Quick Sale is a bit of a misnomer; it takes around five days to ship an item to eBay Valet and two days to inspect it. So you can expect to be waiting between 7 - 10 days before receiving your payment.

Additionally, be aware that Quick Sale won't take every one of your unused smartphones. The devices won't be excepted if they are too old, in poor condition, or are worth less than $100.

It may eat up a lot of your money in commission, but Quick Sale does at least guarantee that you'll be paid for the phone. There are plenty of people who would rather let someone else deal with selling their second-hand goods, no matter how much cash they'll potentially be losing from a sale.

Should Quick Sale prove successful, the program may eventually be expanded to cover other items.
