Seriously, you people make me shake my head in amazement. When the item arrives at QVC, what do you think they're going to do with it? Re-sell it? They can't. QVC is either going to dump the liquid out or throw the entire item into the garbage.
The item did not satisfy the customer. It doesn't matter if that happens on the first drop or the last drop of the product. As long as it happens within the return policy period, the customer will receive a refund even if a couple of empty bottles show up at QVC's doorstep.
