What is the ruling on buying through an intermediary from international websites for a commission after presenting the cost and obtaining the client's approval?

There is no objection to dealing with websites that act as intermediaries for purchasing international goods for a commission, because this is considered an agency for a fee, which is permissible, provided that the good is permissible and the transaction is lawful. Therefore, it is not permissible to purchase gold and silver due to the lack of immediate possession. The intermediary guarantees the good in case of its destruction or damage because he is a joint hired agent, which is the view of many scholars. Furthermore, the website's commitment to guarantee in the event that the seller is an internet scammer is permissible; this falls under the category of conditional suretyship and guarantee of liability and defect, which is permissible according to some scholars.
