Amazon.com and Barnes & Noble's websites, in addition to Lulu.
If you're in Canada, you can find DRZ #1 at Amazon.ca or Lulu's Canadian store.
I only have a few print copies remaining in my possession, so it's coming off the Hog Town Games' Big Cartel storefront. I'll keep these copies for promos and giveaways and whatnot. Of course, you can still get the current Dice Roll Zine #2 in print from the Big Cartel storefront.
Thanks for reading!
