I've got Maxim until Dec 2008, Stuff until Nov 2010, and FHM until Sep. 2007. With my luck, I'll probably come across deals to extend all three before they run out.
Beyond that, I have EGM, and Tips & Tricks until early next year (don't remember the exact months they run out at the moment), Blender until next January, and TV Guide for another month or so.
