Clothes (when they fit are lovely) however when you return an item you are refunded the sale price regardless of whether you pay full price or not. Both of my last two refunds (5 items), which I paid full price for, have all gone into sale so I received sale price refunds. Technically this is theft. You also pay £2.50 for a refund which is deducted from your refund as well.
There is no way I can find how to contact Shein other than a telephone number and the number is foreign so would probably cost a fortune to ring. Really awful procedure and this needs to be changed as they will be raking thousands from people.
