eBay is the largest marketplace for Xbox One consoles. It offers the most variety, from the original "VCR" model to the slimmed-down Xbox One S and the powerful Xbox One X. Competitive pricing and rare bundles.

Ensure an official wireless controller is included, as buying one separately adds $40–$60 to your cost.

Direct-from-owner deals without the "sketchiness" of Craigslist.
