In what is being described as a computer glitch,'s Top 100 Book List was filled with comics and graphic novels after a computing error heavily discounted hundreds if not thousands of graphic novel titles. First reported over the weekend on the comics news blog Bleeding Cool, news of unbelievable bargains spread quickly on Twitter, and readers flocked to Amazon to place orders for graphic novels at wild discounts. Prices included high end boxed set hardcover collections, really priced at more than $100 but suddenly offered for $14.99 or less.

A source at Diamond Comic Distributors, which supplied the comics to Amazon, said the mispricing was a data error and that it was being fixed. It is unclear how many items were ordered during the period of mispricing although there is speculation that there were thousands of orders. It is also unclear how many—if any—of the orders Amazon will honor.
