The deal will give Londis retailers the chance to try an ATM machine for three months free of charge, a higher commission rate on self-fill machines. The first 50 self-fill machines will be reduced by £500.
According to the symbol group an ATM in the shop could deliver around £11,000 of extra profit each year.
Trade marketing director Ross Halliday said: “Independent research shows that customers value an ATM more highly in a convenience store than a lottery terminal or a post office.”
One in four Londis stores currently has an ATM.
