oh and if a scammer did it to you and successfully won a case on this basis, would you be so smug then ??

It's a bit of a stretch to suggest that a scammer would go to such lengths as to post something of identical size and weight to the same postcode in which I live. I suppose it's theoretically possible, but it's also possible that I could get abducted by little green men tomorrow, it's just a risk that I have to accept and if I'm not willing to, I ask for registered and insured (the parcel that is, not the little green men!)

For what it's worth she now has an eParcel contract so hopefully no more issues.
