restocking fees

More high end manufacturers are selling direct and offering home auditions, and many are charging restocking fees of up to 20%. I absolutely respect the right of any manufacturer to charge whatever he sees fit. It's expensive to have product in the field, and companies want to discourage tire kickers, but I see no reason to risk paying a restocking fee when the market offers me so many other choices. Do restocking fees discourage you from trying a product, or is the risk worth taking.
