Hunstanton’s lifeboat’s operations manager, Robin Rafferty, was presented with a cheque for £5,000 for the RNLI on Sunday.
It was handed over to him by J and J Wilson Shops director, Scott Lloyd, and Old Hunstanton employee, Michelle Rayner.
The company operate 78 outlets around the UK coast including their Post Office and general stores in Old Hunstanton.
Mr Lloyd, said they believed in supporting worthwhile local causes.
“We’ve donated money to the Hunstanton boat before by raising money from a charge on the carrier bags we use in our shops.”
J and J Wilson is part of NISA, a national group of independent stores owned by members.
This time the money is from a NISA campaign dedicated to making a change locally.
Mr Lloyd said: “We get a rebate on all the NISA branded heritage products we buy which goes into a fund.
“The £5,000 came out of that fund and we chose to give it to the Hunstanton RNLI.”
Lifeboat press officer, Geoff Needham, said the RNLI was a registered charity which retires entirely on public donations to keep their vital service running.
“We don’t get a penny from the Government.”
Inshore and offshore state-of-the-art lifeboats are expensive both to build and maintain.
The largest Tamar class lifeboats cost £2.7 million each with inshore hovercrafts ringing up the till at around £300,000.
Currently the RNLI needs over £400,00 a day to maintain 125 stations around the United Kingdom.
As at the nearby Wells station the mainly volunteer crews and shore staff of both stations face the North Sea, reckoned to be one of the most dangerous in the world.
“We are extremely grateful to J and J Wilson, one of our local supporters, for their most generous donation,” said Robin Rafferty.
