Gamestop currently has a "same as cash" deal where you get the same amount in cash as you would in credit. $90 for an OG 500GB Xbox One with controller and cables.
$110 for the Xbox One 1TB that I have, but they don't have the "same as cash" deal in CA. Still might go for it and put the credit down on a pre-order of RDR CE and cancel my pre-order for it I currently have, since that's the only GS exclusive I want right now. Craigslist is really risky as far as I'm concerned.
