SuperValu Ballymun is organising a food collection every second week to help people sleeping rough in the area.
The business reached out to Ballymun Soup Run organiser Jeri Byrne with the idea that has since proved to be a massive success.
Robert Murphy and Mick Nan were eager to help those without homes in Ballymun in any way they could.

Robert had previously supplied the soup run organisers with most of the supplies needed for Christmas dinner.
Locals are being encouraged to pop something extra into their trolley if they are in a position to do so and then leave it on a table set up outside.
Jeri told Dublin Live that she was blown away by the men's kind gesture.
She thanked the staff of Nan's SuperValu Ballymun for pulling together this week for the first collection.
She said: "They are both amazing support. This is what we need- Ballymun supporting Ballymun.
"They were both reared in Ballymun, have their own business but they never forget their own people.
"They don't only come out at the festive season. They help all year round too.
"Without the likes of Robert, Mick and the people in our community- it would be very hard to run our table weekly.
"We serve 150/200 dinners on a Sunday evening alone, so this will be a tremendous help to us.
"Robert and Mick never forget the people of Ballymun."
