I agree with you all about the postage. The other day I returned an item (first class) to QVC and it cost just over £1. QVC sent it 2nd class and charged me £3.95. I don't think a jiffy bag costs £2.95 !!!!
I imagine the P & P charges are to discourage people from just ordering stuff and sending it back. If you know you will lose £4 - £5 in P & P it makes you think before ordering rather than just ordering indiscriminately.
There are several reasons i've stopped using QVC but by far the biggest is the rip off P&P, as I see it they are charging me a small fortune to cover losses they make on other people and that isn't right.
IMO free postage or a postage cap (ie order as much as you like in one go for one amount) is becoming the norm on the internet now, even on other shopping channels. Not only do QVC not offer such deals but they also charge ridiculously high amounts.
