Club membership allows all adult customers to collect "liters" on their ISOMAX card with each purchase.
By advancing through three levels: ISOMAX, LOYAL and ROYAL, depending on the amount of collected "liters", the customer realizes numerous benefits.
The liters collected in this way can be used as a means of payment for each subsequent purchase. In addition to collecting "liters", ISOMAX card users receive a refund when buying in Euromarkets on all consumer goods except electronic telephone refills, tobacco, tobacco products and printing.
