We do bargaining for a living. For example: If the price of a car is Rs.1000000, we sell it for Rs.1200000 on installments for a period of 6 months, and repurchase it for Rs.1000000. Is this permissible, or is this considered as interest?
The aforementioned procedure is just an alternative method of benefiting from interest. This is not permissible as per Shari'ah. This must be avoided.
And Allah knows best.
