Someone returned clothing to the store for whatever reason (wrong size or colour etc) . THe store does not refund money but gives out credit notes to ensure that the buyer comes back to spend the credit. Someone is trying to sell her credit, at discounted price in order to get her money back. Is this permitted or is it a form of stealing?
It is permitted to buy the credit notes at a reduced rate since no one is forcing her to sell her credit notes for less than what she paid. She is interested in getting her money back quickly so therefore there is no problem to buy it from her.
