I've realised I have bought an external hard drive from them in the past.
Possibly ink I think as well.
I/my brother buys 25 dual layer DVDs every maybe 6 months from there for his XBox360 games. Just bought some this week actually.
It's certainly worth doing since quite a lot of people buy from there, any money is better than no money.
