Are they a great deal? Not all of them - but, seriously, I don't think lots of them ever were. But TV shopping was new and different, not much was available online, and we all went for them.
There are still excellent TSV bargains - which to me means I can buy something I want for less than I'd pay some other day and that's always good as far as I'm concerned. I quit long ago following the TSV's and ordering things I hadn't been thinking of buying.
I can't speak to the Q's clothing quality because I buy so little, but I think clothing quality is down lots of places. I buy most of my clothes from Nordies, but each year I reject more and more of what they offer as much because of quality as because of style. It's just not what it was until/unless I'm willing to spend way more than my life style and wallet call for.
As for the amount? I find it strange that $5 or $10 less for an item is nothing, but so very many people complain about paying that amount for shipping. IT'S THE SAME MONEY whether you're saving it or spending it.
