Do they pay fair prices for people selling their cards?

I only have experience selling MTG cards here but I can tell say with confidence I've never been offered an unfair price. Make sure you have a good idea of what your cards are actually worth (not what they are worth to you) and if you dont get it be prepared to walk away, they arent running a charity.

All depends on what you have. If we don’t have something and want it pretty bad we will pay pretty high. Other times we will tell you if we aren’t very interested or if we already have a lot in stock and are paying lower than the standard rate of 30-50%. The lower side for a less expensive item and higher for more expensive items.
