The Kickstarter is funding the series but the offerings here for physical books only include issue 1 and offer a ton of really exciting and cool limited edition Kickstarter exclusive covers that are only available to those quick enough to hop on board this campaign.
You can get the whole series digitally through the Kickstarter, if that's your thing.
Issues 1-4 (or 5 if we hit the stretch goal) will be printed, though, and available in comics stores, online shops like midtowncomics.com or mycomicshop.com, and hopefully with music/merch outlets too! In other words, they'll be super easy to get ahold of.
There are a few reasons we're not offering the printed versions through the Kickstarter (shipping 4 times for 1 Kickstarter is hella expensive for everyone involved, for example) but the main one is GWAR gets the whole profit share when the books go to retail and we don't want to take from that - so buying the books in stores when they're out helps that retailer and sends dough to the band.
