Okay So I ordered my items on Friday and Saturday using Super Saver like I normally do, expecting them to be here around Tuesday. Instead of sending them out using Royal Mail like usual, Amazon have sent them to me using HDNL and provided a tracking number. Using that tracking number, I can see that my items were "Out for Delivery" both yesterday and this morning, then "Returned to depot" less than an hour later in both cases without a reason given.
Looking at the Amazon UK forums it seems a lot of people have been having problems with their delivery lately
I just hope my overpriced Twilight box gets to me in one piece!
