We like Flipsy, a trade-in comparison site that will let you know where you'll get the most money for your item.

Some sites, such as Flipsy, offer easy comparison of prices among several sites, some lesser-known.

Flipsy offers a price history chart and a private party value, similar to Kelly Blue Book for cars.
