If I had read some of the reviews below, I would have been discouraged from ordering from Zalando. But thankfully, this is the first time I have come to review so they are new to me.
What I have experienced from Zalando is absolutely fantastic service. I ordered an item from Germany on 16th October and it was with me in the UK by the 20th. The exact day they guaranteed. The items are comparatively cheaper (although there can be some overnight hikes!) and they have a wide range of goods. 5 items shopped this year from them and all delivered within a week from Germany. No amount of negative reviews can change what I have experienced from this group.
