I have been using Zalando for a year now and all my deliveries have arrived on time. Generally i think they have a good range of clothes, and they appear to be totally genuine (big brand names) looking at the stitch work etc. 2 problems i have had with them. 1. Hugo boss shoes arrived in a brown box, got through to their customer services to be told the original box was damaged and that their selling the shoes not the box. I laughed and just hung up and returned them hassle free (collected by Hermes). 2. Deliveries take on avg 5-9 days from ordering even if you pay for next day (i don't get that!?!?!) but if you set your mind when purchasing knowing it’ll be a little wait, it’s not the biggest of issues waiting a week for a bunch of clothes you didn’t have to hit the high street for, shuffling shelves and rails. Will continue to use Zalando.
