I use lovefilm, get 2 dvds at any one time and is unlimited rentals per month and there are different packages. I pay about �13 per month and the turnaround from me sending dvds back to getting new ones is about 3 days. Postage is also free
Yes, that is what I was about to say, although I have never used that service myself, I am told it is very good. I think Tesco also offer the same service, and the Odeon cinema chain as well, although I am pretty sure you can only have 2 discs at a time, and they will only send you new one when you have sent back the old ones.
