I have the best experience with Mytheresa for luxury goods. Purchase and return are free as long as you spend over €200. Occasionally they have promotion for free delivery for any purchase. The Pickup refund process is Super easy. Order a pickup service from DHL online takes me about 1 min, courier will pick up the package. Refund is received within 5 working days, mostly 3 working days for me from the day of pickup. Customer service is superior. I never had to wait, customer service pick up the phone immediately. Very good stock, fantastic purchase and return process, efficient customer service. The only suggestion is the website could do with some updates. Hard to pick more than 1 size in filter. Not sure why I need to log in every time when I check my account? Since I have face login, it doesn’t bother me that much, but still find it a bit inconvenient. All in all, Mytheresa is the best luxury online shop in my opinion!
