What Are Your Comic Books Worth?

Need to know what your old Superman, Wonder Woman, or Batman comic books are worth? Need a price for your Amazing Spider-Man, Avengers, or other Marvel Comics? Trying to buy or sell your comic books? Looking for variant covers to recent Star Wars issues? Whether you are a new user, or one of the 25,000 migrating over from our iOS app, the all-new Zap-Kapow is ready for you.

Zap-Kapow is an online comic book price guide. We have been surveying prices for comic books online, and bringing them to iOS users, since 2009. Needless to say, a lot has changed since then, including how our users want to use Zap-Kapow. We heard (and heard, and heard) from our users that they loved Zap-Kapow’s comic book price guide at their local comic book shops, flea markets, garage sales, and comic cons to find comic book prices and references, but something the original iOS app was never intended to do was also something everyone wanted; full collection management.

Comic Book Price Guide and Management

With the new Zap-Kapow, we are finally giving users the ability to add, manage, and print your FULL comic book collection, tied in with our digital price guide engine.

The entire app engine has been rebuilt from scratch, for even more devices and operating systems (welcome Android, OSX and Windows users). Anyone with access to a mobile or desktop browser can now enjoy Zap-Kapow!

So if you’re new to Zap-Kapow, get started by clicking the Sign-Up link above and then picking a Zap-Kapow account plan that works for you. If you have previously purchased the iOS version of Zap-Kapow don’t worry, we have you covered. You can migrate your account over to the Bronze Age Plan for free using the steps below.

Welcome to the new Zap-Kapow Comics.

The iOS App's Future

The iOS app in the Apple App Store does NOT tie back to this website. For the time being it will continue to work, but anything you add there as a Favorite, or any price guide updates you purchase there DO NOT carry over to this web app. Eventually, the iOS app will be retired in favor of the version of Zap-Kapow you are on now. We recommend you use this version for purchasing price guide updates and creating favorites lists exclusively.
