They got rid of a strictly beauty channel more than two years ago when they stopped live programming there. Ever since, it as been a a catch-all channel for whatever programing QVC wants to re-run.
What they should do is rename the channel, but they probably don't want to really call it QVC 4. So until that time they rename it, there will continue to be all kinds of items on that channel.
[Remember, for the past two years it has even been the " best of holiday items" channel for three or four months of the holiday season.]
