I try and use recorded delivery whever possible, but sometimes the item isn't worth much, and it is easier to just stick a stamp on and put it in the post box.

As for PayPal, I would never get them to force the seller to give back the money, unless I was convinced that the seller never posted it. I tend to trust most sellers (and buyers).

On the good side of things, my Special delvery driving license application arrived before 1 o'clock today as it should have done, so I am very happy with that.
