Was a member 2 or 3 years ago, it was/is a great service but we found we just weren't using it as we should. We were paying a tenner a month which got us three dvd's at a time, problem was we were just rubbish at sending them back, so we would have films lying around for months on end
so we cancelled the service. No slight on them it was us.
And as Tench says keep your list up to date, if i remember rightly you need to keep 10 films in the list in order of priority. If they are out of one they will send the next on the list, although this never happened to us as we always got our first choices.
So all in all if you use it right and watch a lot of films then go for it as it works out alot cheaper.
I've been thinking about joining again as they now have a streaming service, so as soon as I get round to buying a dongle for my TV to connect to the network i'm gonna try it out. Word of warning, when you buy a Samsung TV that claims to be internet ready, read the small print! £50 extra for the dongle:mad2:
