Magazines are very hard to get rid of, I have thrown hundreds of them on the local city dump as nobody was even remotely interested, not even for free !! The same goes for floppies, everytime I offer them for free pickup I get absolutely no response.
About the real hardware, Ebay is the place to get some fine prices, though they are not always the same. If you´re going the Ebay way then be sure to offer worldwide shipping at a reasonable price :-)
