Used someone’s Rav Kav / avak ribis

Question:

Hi,

I used someone else’s Rav Kav for one ride. How much do I need to pay him back? The cost is technically 5.9 NIS, but if one has a Rav Kav the cost is really 4.72 NIS (The company in charge of the Rav Kavs gives you 25% more than what you pay for when you use a Rav Kav for payment.). Furthermore, it is not possible to pay 4.72 NIS. If I pay him back some rounded number, how can I avoid the problem avak ribis?

Thanks in advance!

Answer:

Thank you for your question.

The value of a bus ride is 5.9, therefore that is what you have to pay the owner of the Rav Kav.The fact that he got a discount is because he bought a number of rides, and it isn’t any different than a store keeper who gets a wholesale discount for buying bulk, and sells it for the regular retail price.
