Yeah it’s been slower for me too, with Lovefilm if you sent a film back up to about Tuesday you’d be pretty guaranteed to get its replacement by Friday. I’ve posted stuff back to Cinema Paradiso and not had it turn up in the ‘Returned’ list until almost a week later. However I did start in November so I’ll put it down to Christmas/weather-affected deliveries with all the storms and that for now.
Also not been amazing at sending out discs from anywhere near the top of my priority list (tbf Lovefilm weren’t much better, you could have the same film at the top of your priority list for months and not get it). We’ll see how it goes, I too would rather have blurays than try and stream over a shitty internet connection so I don’t think there are many other options.
That said, Spiderman Homecoming is on the way.
