I've seen them at the Borders I go to. Unfortunately, it's in the Men's Interest section, which I think is misnamed and paints nudism in a bad light. It's up there next to Playboy, Maxim, FHM, and Hustler. Also, are the tattoo and cannabis mags, which should go to the art and home/gardening sections, respectively.
And why on God's green earth is Playgirl in Men's Interest?
Unless you consider the gay men that might want that magazine.
