Walmart offers preorders of Justice League on Blu-ray / DVD / Digital HD bundled with six Justice League pins for $27.96 with free shipping. That's $17 off and the best price we could find. (The Blu-ray alone costs $25 elsewhere.) It includes emblem pins for Batman, Superman, Wonder Woman, and the other three. Note: It's due for release March 13.
