Is there any suspicion of unlawfulness concerning profits made from using multiple accounts on discount websites to repeatedly obtain offers, while paying the full price for purchases?

If websites grant a discount once per customer and do not allow more than one account, it is impermissible to benefit from the discount more than once, as it constitutes prohibited deception and fraud. However, if websites allow access with multiple accounts and grant a discount for each account, there is no harm in benefiting from the discount, as long as the registrations comply with their specific rules and regulations, without deception or forgery.
