How the PP card works

When you use the PP card and add to it € 40 you get a € 6 bonus. Therefore, when you pay for laundry services using the PP card, part of the standard price you pay from your own money and the rest of the standard price you pay from the bonus money, i.e. from the € 6.

For more clarity let's take an example. You put on the PP card 40 € and use the 10 kg washing machine (price € 5.00). Since you put on the card € 40, you receive a € 6 bonus. Therefore, when you pay for the laundry service, you pay € 4.35 from your money, i.e. from € 40, and the remaining € 0.65 is paid out of the € 6 bonus. So, it turns out that the price actually paid by you is lower than the actual price on the receipt, i.e. € 5.00.
