Last resort : Count the bill of your purchase your self and buy or leave one more item so that total bill comes near xx.80 to xx.90 , this way you can have a benefit of saving approx 15 Dirhams on all your about 48 visits / year to supermarkets & you stand to gain a good amount in 5 years.

God bless all !!
