Yea they are great on the lose of other people's money. Basically They don't care it was done so they can win and you just loose your money. At least you got a package. I just got nothing but my money taken.

Dear customer,
Nice day.
Thank you for your support.
Sorry for the late reply and the inconvenience we have brought to you.
We have checked for you and found that your order have enjoyed the coupon discount.
Our web has noted that the coupon discount is based on the original price of each item. If the item is on sale and has a larger discount than the coupon discount, then it will use the sale discount instead of the coupon discount. Attention: One coupon per order. Hope you can kindly understand.
If you need further assistance, please contact us via dispute@shein.com.
Thank you for your support.
Best wishes.
