Just an FYI, the Q&A section in Google is designed to post questions to the community of reviewers, not directly communicate with the business. For very specific questions like yours that require the business to respond, you're better served calling them up. Good luck! They may even give a price over the phone.
From my experiences here, they have at the very least given me a fair price for any game related merchandise I've brought in, typically they base their valuations off of market trends is what it seems like to me, that is my opinion, I do not work for capital games, couple years back I brought in some rundown old ps and Xbox controllers they gave me a couple bucks for them, love this place and staff is the best
