I use recorded delivery a lot through the year to send racing info to the NFC etc,they allways ask me if there is anything of value in the envelope, just had a look on one of the little recorded delivery slips I fill in to send the envelopes, it states,We do not pay compensation for money or jewellery or other items of value sent Recorded,USE SPECIAL DELIVERY INSTEAD.Looks like you were imformed wrongly as to which service to use.
Sorry put the above on the wrong thread somehow can somone put it on the correct one.
