I miss both channels terribly, as someone who likes to have the tv on in the background while going about my day. A few times a day I've been putting 645 and then 654 on, just in case, just to check, you never know, in hope.
I'd lost interest in Shop at Bid pretty much but was glued to the car crash that was Pricedrop for the last couple of weeks, couldn't believe what i was seeing, couldn't switch it off.
I've been watching sit-up's channels on and off, pretty much since inception, with varying levels of interest over the years. I accept they have gone, but it's going to take me, and my channel selection finger, a while before I stop looking for them. I've looked through the remaining shopping channels lots of times, and none of them are going to be able to fill the gap left by my old friends at Sit-up.
Watching lots of Youtube clips over the last few days has just served to remind me how much more fun shopping tv used to be, and that we are in a pretty fun-free state right now.
