Michael Smith, Ryan Searle and Mark Webster will take to the oche for special challenges against fans at Selco Builders Warehouse next week.
The leading builders merchant will host rising star Searle, the world number 16 and Sky Sports pundit Mark Webster at its Exeter branch on Tuesday April 26 between 1000-1200.
The event will form part of the celebrations to mark the opening of the Exeter branch, which will be based on Filmer Way in Marsh Barton.
On the same day, World Championship runner-up and Premier League star Smith will be appearing at Selco Liverpool, on Galgate Drive in Bootle, between 1000-1130.
At both events, members of the public are invited to come along to the branches to take on the players in special nine-dart challenges for the chance to win spot prizes.
Selco, one of the UK's leading builders merchants, is an official partner of the Professional Darts Corporation.
Carine Jessamine, marketing director of Selco Builders Warehouse, said: "We are thrilled to be hosting Michael, Ryan and Mark across two branches in what will be an exciting day at Selco.
"Michael proved at the World Championship what a talented player he is and will be a real attraction in Liverpool.
"The darts activity will be a big part of our celebrations on the opening day in Exeter.
"Ryan has broken into the top 16 players in the world and Mark is a household name in the sport, both from his playing career and his television appearances.
"There is no need to book for either event – just visit either Selco branch for what will be fun and exciting events."
