If QVC consider a customer has returned 'too many' items under their 30 day 'unconditional' (yeh, right!) money back guarantee then they will send 'the letter' informing said customer, and warning that their account may be closed if their returns rate doesn't imnprove. I think the rate is over 50%-and it relates to number of returns not value. So if you send back 3 out of 4 items but retain a very expensive item, they will consider that too high. Anf annoyingly, when it happened to me they had included several items returnded due to wrong item/colour size sent and an item that arrived broken! I argued my case and they have never spoken to me about it again ( about 2 years ago, now.)
