Just a quick mention to Blockbuster's online DVD rental scheme. I have just joined this and got a Two Week Free Trial (3 DVD's at a time, no late fee's, free postage). Once the free trial is over, it is just £13.99 a month for as many DVD's as you can watch!

If games are more your thing, you could always try Gametart, who do a similar thing with PS2 and PSP games. Again there is a free trial, and then it is just £2.99 a week for unlimited game rentals.
