I ordered 2 items from Amazon on Sat 22nd and paid for Express Delivery by Royal Mail Special Delivery service. Both items were guaranteed for delivery today (27th December). One item was coming from Amazons Glasgow warehouse, the other from their Milton Keynes warehouse. Neither have arrived, and Royal Mail tell me they are still in their Glasgow sorting office and Milton Keynes sorting office. As these are the 2 main Amazon warehouses, I'd hazard a guess and say that this failure to deliver affects a lot of other Amazon customers who opted & paid for Special Delivery. Having already lost one major contract with Amazon, Royal Mail now seem determined to jeopardise their Express Delivery contract too!! I'd really like to hear from anyone else experiencing the same problem.
