I meant to blog this earlier today to give you guys a heads up, but I totally spaced it. (What? Kanye West’s Graduation leaked, and I got distracted.) But okay, here it is, a bit late but still good: If you’ve got some cash burning a hole in your pocket this weekend, Excalibur Comics (2444 SE Hawthorne) is having their usual huge-ass Labor Day weekend sale, with 50 percent off all back issues. (Yes, it’s pretty much as awesome as it sounds.) The good stuff usually gets snatched up pretty quick, so head over there ASAP if you’re interested—the sale runs from today through Monday, so here’s your chance to fill in those holes in your collection or just buy a whole bunch of crappy comics you’d never pay full price for.
