Apparently Powell's warehouse in Northwest stopped buying books a few weeks ago. Kind of a bummer—I liked selling books out there. Lines were rarely too long, and there were fewer depressing college students trying to sell textbooks they paid too much for in the first place. I dropped an email to ask why the warehouse stopped buying, though given recent layoffs I doubt it's anything more compelling than that; if I hear back anything interesting, I'll update.
In the meantime, don't bother schlepping your boxes of teenage vampire porn out to industrial Northwest. The other stores are still buying.
