ET, if she uses Royal Mail International Signed-for, that provides insurance up to 500GBP. But as
nawth21 correctly stated, if you opt for Parcelforce Datapost, you can purchase more insurance. Parcelforce comes with 150GBP insurance by itself but if you'd like more, you just have to pay for it. The postage for Parcelforce Datapost is very expensive, esp for a heavy item but it's FAST! When I bought my regular Paddy off another UK seller, I paid 66.30GBP in postage (to Australia), and that's without extra insurance. It offers full tracking so the chances of it being lost are very slim. However, if you just use Royal Mail International Signed-for, that only offers limited tracking so you'd be paranoid a couple of days while waiting for your package
