Advice for selling PS4 and Xbox One

Been lurking for years now, so hello!

Just as the topic says, I have a PS4 base model (has a 2tb HDD I installed) and my Day One Xbox One (controller is long gone as is kinect) that I just want to get rid of at this point. I only have a few games, I already wiped the drives.

Is Gamestop my best bet for a quick turn around? I do not want to deal with a pawn shop or ebay unless the difference in price is going to be huge.

Both systems work great, I had the Xbox fixed by Microsoft when the drive started acting up and within the last year I opened and cleaned the PS4 really well and put new thermal paste on everything.

I just do not use them, I play my Switch constantly though.

Thanks!

Gamestop is running a $50 bonus trade in credit for systems, you'll get $160 credit for a PS4 (no extra for the 2TB HDD), but I don't think the bonus applies to cash. If you eBay it, you'll probably net to something like $130 after fees and whatnot. Works for the Xbox 1 too but I think you need to trade in a controller but you might get something on eBay since it is the day one edition. 

No clue on the Xbox 1. 

You could also try the forums here to sell for cash if you wanted. 

Could also try local Offerup or FB, or Craigslist? Just list it 20-25% higher, maybe $200 ish per console?
