The club's president, Derek Williams, thanked Sam Palmer, of the Spar Store, Narberth, who had donated the voucher.
"We are again very grateful to the Spar Shop for its generosity in donating this voucher and to the staff at the shop for their support when Rotarians were at the premises selling the tickets," he said.
"We are also grateful to the people of Narberth and the surrounding area for buying the tickets.
"As a result, nearly £1,000 has been raised for Rotary causes and charities."
