Is it permissible to join the network marketing company "Forever" by purchasing products worth 200 Saudi Riyals to obtain a 30% discount, then using or selling them without establishing a group or recruiting members?

If the subscription is free, it is permissible to buy and sell lawful products from the company. However, if the subscription is for a fee, it is not permissible, because it leads to jahalah (uncertainty) in the purchase price. This is because the subscription fees will be part of the price of the goods, which results in the forbidden jahalah in the sales contract.
