There is concern from some retailers. A few I'm thinking of wrap in tissue paper, then stuff some around the item to keep it from moving around in the "box." Also included are hangers and reuseable garment bags.
I wouldn't expect that from QVC, though, because that would add to the cost, then customers would complain about rising prices.
Also consider shipping costs between a box and a small lightweight plastic shipping bag.
Most of what I ordered from QVC did come neatly folded. I think many of the wrinkles come from being stacked on top of each other tightly on cargo ships and in the warehouse causing the wrinkles to look like they were ironed into the fabric.
Some of the wrinkles were difficult to get out. I'm thinking leather jackets and other fabrics.
What annoyed me most are breakables packed with flimsy foam and boxes.
