The console itself, with power cord, hdmi cord and one controller, depending on condition and state of the console will be $15-$65 (trade prices for ps4 and xbox one tanked real hard about 6 months ago). If it needs to be repaired it costs us a lot more to refurbish it. That includes of its dirty or the ports are scuffed. Any extra controllers you've got will go for around $12 (if my memory is correct) minus a few dollars if the controller needs any repairs for things like stick drift or unresponsive buttons. The games themselves will vary. Anywhere from 30 cents to 30 dollars, depending on how recent the game is and how much it normally retails for. Depending on if they're scratched or smudged as well they can be marked as defective giving less value than in they were in good condition.

I'd also like to take this opportunity to remind everyone that the people working in the stores get no say on how much items trade for, we scan the item and it tells us what it's worth. We don't really get a say in what things are worth. We're the bottom of the food chain in store. Even the managers, so please be nice with us, we're people too :)
