They never seem to reduce the price, they just add a "free gift" like the in-ear headphones they were giving away with the "bargain item" tonight (a portable sound-dock).
But if you look at the Bose ads in the press, they invariably add a free gift too, and give free postage, easy payments, and a 30 days trial, so QVC TSV's are not especially good value, and often, you do not need or want the free item.
The Wave radio they were selling tonight was NOT the current version that now has built-in DAB. Also, they were flogging it with a 3-CD changer, and using CD's is old hat these days, so no-one would really need FOUR of them in the same unit IMO.
