We have kept the Sky + as it means that we have loads of stuff to watch if we can't be bothered / afford to go out. It gives us free internet anyway, so is pretty good value.
Joining the library is a great thing to do. I am a big reader and own thousands of books, but I can't buy them anymore as a) I have no space on my shelves b) I am skint so going to the library for books is a great thing. They also have a great range of CD's and DVD's, as well as tapes and videos, so it is all much cheaper than buying anything, or even renting.
Food I think is the main way people can cut costs, and there are hundreds of threads on how to save money there.
Moneysavingexpert I agree is genius. Planning a wedding during a recession is not an easy thing, but St Martin Lewis has made it all so much more doable. We are going to be able to have a great wedding at about a quarter of the average cost.
