That's a strange claim given that we're talking about a "contract" which QVC has no proof that the other party read or agreed to, and which there has been no explicit exchange ("offer" and "acceptance").
Are web-site contracts/terms even enforceable at all? According to this article[0]/case law likely not. Strange thing for a lawyer to say, but this article makes a lot of strange claims that seem inconsistent with US case law.
