This website exists but I can't remember what it's called. I did originally read about it on mumsnet so hopefully someone else knows of it or can help me find it.
Literally, you type in the film or tv programme's name and then you're given all the possible options for viewing it. So you might be given details of Netflix/blinkbox/Amazon if it's cheaper to buy/cinemas if it's showing.
I have Netflix and don't want to commit longterm to other subscription services, don't want to buy a dvd everytime I want to watch a film (and sometimes want to be spontaneous).
Does anyone know this website or have any other suggestions?
