In a supermarket, when paying your bill amount, if your amount exceeds RO.100, You have an option of Cash or Credit Card. If you pay as cash you will get 6% of discount from your original amount, but for Credit Card there is no discount. When your amount is less than RO.100 you will have to pay by cash only with the discount of 3%.
