The cost of fraud has to be passed on to all buyers in the form of higher costs. Because of this all reports of lost items are reported to Royal Mail who may contact you to confirm the circumstances of the loss. For your security and to minimise theft, where the item is valuable or you have a history of non-receipt we may also ask you to repo.
