LongBox, a new digital comics platform that's aiming to become the iTunes of comics, is about to launch its new Beta version at Emerald City Comic Con in Seattle this weekend. But while most of the world will only be able to read through a few watermarked sample comics until the wider release, ComicsAlliance readers will have an opportunity to get a wide range of comics through LBX before the general public -- and get them for free.

While LBX is still in Beta, we're going to be giving away 15 gift codes worth $25.00 each to 15 ComicsAlliance readers, which can be used toward anything in the LongBox store. With most LongBox comics priced at just $0.99 (and digital graphic novel collections priced around $5 to $10), winners will essentially walk away with up to 25 comics or several trade paperbacks.

Publishers like Top Cow, Boom!, Archaia, NBM, Shadowline and more have already been announced as participating, and will be offering their comics through the LBX store, along with creator-owned projects from individual creators like Jonathan Hickman ("Fantastic Four").

All you need to do to enter the giveaway is head to the ComicsAlliance Facebook page, and answer our poll question about digital comics by 6 p.m. EST on March 16. Read the Official Rules for the fine print, and if you're curious about what Longbox will look like, check out our exclusive pics of the new Beta version after the jump.ComicsAlliance's LongBox giveaway is open only to legal residents of the 50 United States, the District of Columbia and Canada (excluding Quebec) who are 18 and older.
