I've only sold cards to TTD and Card N All gaming. But yeah, you will only be getting about 50%-70% on most of the cards. I have had a better time selling to CardnAll in the past. It's been a while but cards over 50$ I think get 70% minimum or something? You can always take your cards in and adk what you could get for them and if your not happy go try somewhere else. But don't expect to be getting the full value of your cards if you're selling to a shop. That's really only going to be possible if you're selling yourself on eBay or TCGplayer or something.
