Hello,
Thank you for sharing your shopping experience in this store. We will be happy to explain everything to you.
The Premium account does not offer a 30% cashback on the amount of each order, but increases the base rate by 30%. For example: an item with 5% cashback taking into account the Premium account, is 5 + 30% = 6.5%. This discount is applied for one week after having created the account in Letyshops.
We hope we have clarified all your doubts;)
Sincerely,
LetyShops team
