Heroes is an awesome store. First, it's really big. It's thin, but really long (that's what she said). Plus it has a second floor. It's quite possibly the biggest comic store I've ever been to (bigger than Paradise Comics, or Beguiling). Its manga selection is fairly light, but for mainstream comics, it has a bit of everything; and a wide assortment of toys, too.
But what makes the store truly special is its huge selection of discount books. The entire length of the store is lined with comic boxes filled with 50% off books; that's in addition to the whole second floor devoted to the same (along with piles of books for $3.99). It's the only store that can rival BMV for deals.
