price

Q: I am a car dealer. I am not involved in finance. However, I accept different forms of payment, such as cash, EFT and via a card machine. Is it permissible for me to decide the price of a vehicle depending on the customer’s form of payment? The bank charges me 3,25% (for a credit card) and 1,75% (for a debit card) of the total amount if the card machine is used. Can I add this percentage onto the original price of the vehicle? If so, does it have to be the exact amount the bank charges me or can I round off or add to the amount as I desire?

Q: I am in the business of buying and selling car mags. A few months back, I sold a set of rims to someone for R1800. A couple of months later, I got a call from the same person asking if I want to buy these same rims back because he had no use for them. I made him an offer of R1200 and purchased them back. Is this considered as riba or is it permissible?

Q: I run a business buying and selling furniture, gold and silver. When a person sells an item to us, then in most cases, an option is given to the seller to buy back the item sold at any time, if still in stock, but at a higher price. Is this permissible?
