Dealing with the Waseetuka website for buying goods from websites
Question

                The Waseetuka website buys from international websites such as eBay: after the customer has specified the item and the website, the Waseetuka website pays the costs of the item, including the price of the item, shipping, customs duties and insurance, if applicable, as well as a fee to the website. After an agreement is reached, the customer transfers the money to the Waseetuka website, then the website buys the item and ships it. What is the ruling on that?.
Praise be to Allah.
      There is nothing wrong with dealing with the Waseetuka 
      website to buy goods from international sites in return for a fee paid to 
      the website, regardless of whether the fee is a set amount or a percentage 
      of the price, because it comes under the heading of delegating someone to 
      act as a hired agent, and that is permissible, so long as the goods in 
      question are permissible and the transaction is permissible. It is not 
      permissible -- for example -- to buy gold and silver through this 
      intermediary if the hand-to-hand exchange is not achieved. 

    As the intermediary in this case is responsible for shipping 
    the product to the customer, there is no doubt that he is liable for the 
    item if it is destroyed or ruined, because he is a hired agent, and many of 
    the scholars are of the view that the hired agent is liable. See 
    al-Mawsoo‘ah al-Fiqhiyyah, 32/294. 

    From referring to the website mentioned, it is clear that 
    that the website is committed to compensating the customer in the event that 
    the seller turns out to be one of the thieves of the Internet (i.e., a scam 
    artist), and this is also permissible.  

    It says in Fath al-Qadeer (7/183): “It is permissible 
    to connect liability to certain conditions, such as saying: Whatever you 
    sell to So and so, I will guarantee him,” because what is meant is: I will 
    bear the consequences of this sale, so I am liable. 

    With regard to conditional liability, what is meant by that 
    is a guarantee to the purchaser that he will get his money back if it 
    becomes apparent that the item sold is stolen – for example – or it is a 
    guarantee to the seller that the price (for the item) will be paid in the 
    event that the purchaser refuses to pay it… And so on. 

    It says in Manaar al-Sabeel (1/360):  Conditional 
    liability guaranteeing the price of the item paid for is valid, because 
    there is a need for that, such as guaranteeing the money if it becomes 
    apparent that the seller is not the owner of the item, or guaranteeing the 
    price before the seller hands the item over. Among those who regarded 
    conditional liability as permissible in general are: Abu Haneefah, Maalik 
    and al-Shaafa‘i; it was also mentioned in al-Sharh. End quote. 

    See al-Sharh al-Kabeer, 5/84. 

    To sum up: we do not see any reason to prevent dealing with 
    the Waseetuka website for purchasing that which it is permissible to 
    purchase via the Internet.
