But.
It's still worth it here IMO. In fact, Prime here in the UK is about a million lightyears ahead of the US because of the size of the country :)
Free next day shipping is really brilliant for a heavy Amazon buyer like me.
I was actually a Lovefilm user from before the Amazon buyout. I fondly remember the day they were primarily a physical rental service - the warehouse was not far from me and the postal service fantastic. Their catalogue was huge.
Their online service has always been mediocre; about the same as Netflix, Sky and BT.
But the combination of on-demand video and free next day is still worth it to me.
After some research, IMO the combination of Sky (satellite TV with on-demand offering) and Amazon Prime (free next day delivery + on-demand video) is the best combination of price & coverage. I can get 99.9% of the things I want for reasonable price.
Looking at the US service, it doesn't even compare :(
