I'm from the UK and had never purchased from Designer Discreet before. I was nervous about using the WU service as I am unsure what protection I would get - if any at all! But the communications by email was efficient and although my bag was held at customs for a week or so (apparently normal?) and I had to pay about £20 charge (also normal), I received my Louis Vuitton Neverfull MM bag in wonderful packaging.
I have had many compliments and I would highly recommend this website.
