If you want to make some money back from your old electronics, Costco might actually be the best place to trade in those outdated gadgets. Costco partnered with Phobio to launch their online trade-in program in June 2019, but now is a better time than ever to start taking advantage of it. This is a thoughtful way to recycle your old electronics while also cutting costs for your next Costco grocery run. Costco has a trade-in page where you can select your device model and get a quote on its trade-in value. Within five business days of Phobio receiving your device, you will receive a digital Costco Shop Card that you can use in Costco stores or online.
