This place is your best bet for comics or cards. They have other stuff such as action figures and a few rare collectibles. I'm sure lots of kids get yu-gi-oh cards here nowadays, and I'm not sure if they offer the best price. But for Magic the Gathering cards I know the are cheap, as I was recently with my brother as he bought some. Another reason this place is awesome is because they gave away free comic books, which is just cool.
