In reply to Co1in H:
I have had experience with I post parcels - it resulted in me making a formal complaint for Fraud (Signing for packages themselves and then claiming I'd signed for it (I was I at the time too)) and resulted in me having to spend nearly 3 weeks hassling them to actually provide the proof that was required for a refund for the phone that they signed for themselves and posted through my neighbours door (he was away on business for 2 months)
Personally I'd rather use a pigeon than give them any custom.
Post office is stupid prices for anything over 1Kg. TNT, Interlink are both OK for international shipping, but I guess it depends on their pricing structure - My Hermes worth looking at too
