Nearly all my DVDs and CDs are now bought from
www.play.com, and a lot of books too, I bought a leather coat on eBay from a small shop in Wales, and my PC hardware is often bought online - my new gfx card and extra RAM were bought on the internet, it's much cheaper.
Edit: Oh, and some home furnishings like a duvet cover (and some shorts), plus a Le Creuset cocotte, a clock and some mugs
