Excalibur Comics (2444 SE Hawthorne) is once again having their big 50 percent off sale. The sale starts today and runs through Monday, September 1.
I've hit more than my fair share of these since I moved to Portland six years ago, and I have yet to be disappointed with what I've ended up tracking down. This is an excellent opportunity to go and pick up a ton of back issues on the cheap. Do not waste it.
