Scotmid Inverbervie has raised £1000 for the RNLI after its branch manager and grandfather were saved by the group back in May.
David Irvine and his grandfather, Jim Reid, were rescued by the RNLI after going missing in the North Sea during a fishing trip.
The two men were feared lost at sea off the Aberdeenshire coast, and survived on a bottle of water and two biscuits.
They were discovered around 45 miles off the coast of Montrose by another fishing vessel, the Sylvia Bowers DS8.
A second donation of £500 will also be made to local voluntary gardening group, Brighter Bervie, who make the community a brighter place by gardening public areas.
The donations of £1500 from Scotmid have been raised by selling two pence plastic carrier bags to reduce plastic bag use, with 100% of the profit pledged to local charities and community groups. Scotmid introduced the two pence charge for de-gradable plastic carrier bags in 2011 and has now raised over £110,500 for local causes.
David said: “It is a great gesture by Scotmid to donate the funds from selling two pence carrier bags in local stores to the RNLI - they are terrific and a very worthwhile charity to support.
“They are all volunteers with jobs, and it’s a dangerous thing that they do. It was fantastic to see Coxswain Scott Murray again and present him with the cheque - he was in charge of the lifeboat that took us back. They did really well in very tough conditions and we can’t thank them enough.”
