When I wanted to do a project at christmas, I posted on Craigslist and Freecycle requesting magazines.

I was deluged with people offering to let me pick up literally hundreds of copies of everything from Newsweek to Cosmo. I'd offered $10 and was told by the woman I finally picked stuff up from not to worry about the money.

I'm sure you don't want lots of stuff (more clutter, and all) but it might be worth doing.
