In order to get cashback, add goods to your cart only after going through LetyShops and disable other plugins before purchasing.
According to the store's terms and conditions if cashback for your order has not been added to your account with "Pending" status, you should create a corresponding request in your LetyShops account within 1 month after the purchase has been made.
Après 40 jours, le cashback a été crédité sur le compte. Je recommande!
