I sent three parcels and around 20 cards from our local post office here in Cornwall to various destinations throughout the UK and every one was correctly delivered within a couple of days. However. on the flip side, I am still waiting on at least two parcels that were ordered on the 12th December and although the retailer has assured me they were promptly despatched via Royal mail, they have not yet arrived. I think the Royal Mail has become a form of postcode lottery depending on the sorting offices used. It needs a massive shakeup but in the interim, I would follow the advice of other reviewees and check which courier the retailer is using. DPD do appear to be the best at present.
