Online shoppers will be able to pledge their support to a Sheffield-based charity which helps people with tinnitus.
People who shop with Waitrose online will be offered a virtual token to give to one of three charities, including the British Tinnitus Association.
The charity, based on Woodseats Close, Woodseats, will receive a proportion of £25,000 determined by the share of tokens it receives.
Other charities in line for cash are St John Ambulance and Anorexia and Bulimia Care.
David Stockdale, BTA chief executive, said: “We’re delighted Waitrose has chosen the BTA as one of its charities to support nationally.
“This is a huge opportunity for us to raise funds and awareness to enable us to continue to help the 10 per cent of the UK population who experience tinnitus.
“We directly help about 80,000 people per year, and the numbers asking for our help are increasing.
“We provide access to a range of support services, free of charge, available to anyone needing help.
“We wld urge online shoppers to choose the BTA.”
