Members of the Skegness Army Cadets gave up their Sunday to take part in a charity bag pack at Morrisons in Skegness.
They raised £560, which will go to the Skegness Junior Marching Band.
The band is in its infancy and the money will go towards new instruments and uniforms for the children.
The band meets at Skegness Baptist Hall every Monday from 6pm. The cadets meet at the Cadet Hall in Grantham Drive on Thursdays from 6.30pm.
