Inge, if this happens don't be put off returning a beauty set; as long as you return all the component parts in any box or jiffy envelope Q will still refund if it's within the 30 mbg days. Even if you have lost the invoice they will refund if you include your name, address, item number and order number inside the parcel, although it may take longer and I'd probably send this kind of unmarked parcel by a signed for service rather than just getting a Post Office proof of posting so that you can prove QVC have received the parcel should it go astray. Q will usually accept a tracking reference number as proof of delivery whereas you'd have to post the Post Office receipt to them if you don't use a signed for service. HTH.
