It's to be used online.You tick the box when it asks if you have a promotional code.
Did not get a card or email, but figured I would give the code a try. Went online, did tick the box for promotional code, did get the screen to put in the code. Typed in SALE09 and then the red box came up that said it was not a valid code - at least for me. QVC just doesn't love me anymore, not that they ever did! :mysmilie_1950:
