They will buy certain cards yes but I'm sure they wouldn't buy bulk unless they are short on the specific card. They have good prices and if necessary you can always get store credit for the cards you turn in for a little more.
Yes they do. They have a very good selection of yugioh and Pokémon cards along with tournaments
DZ does buy Pokémon cards and unsure about Yu Gi OH card. Best to go in with the cards that you are looking to sell.
