Select books, minis and zines are 50% off in the store, including both Sparkplug and distro titles. You can find the complete list here. There's a lot of good stuff in there, please check it out.
The sale will go until after the Portland Zine Symposium, so if you're broke right now, you'll have plenty of time to pick up books before July 20th!
(If you are a buyer for a store, a bunch of the wholesale list has been marked down as well. Check out the details here!)
