You don't have to imagine. I've sold products on QVC and they don't demand large cuts of the sale. It's 4x your cost. Your selling price to them is 2x your cost. Then QVC keystones it. The issue is that the supplier has to find away to get all their selling inventory to the QVC warehouse a week ahead of the first air date of selling. And the seller is responsible for the freight charges.

If Berman can get $200-$250 per unit then he should ignore QVC for the time being. At some point the timing will be right for him to revisit this. Usually when the product has reached it's maturity level or when he comes out with a newer version and needs to blowout inventory.
