The Manchester Road store is running the campaign for three days.
Customers who shop in-store on Friday 2nd, Saturday 3rd and Sunday 4th August will have the chance to win a £10 voucher every hour at the Manchester Road store.
They are randomly selected via the radio system in the store.
Andy Atkinson, the new CEO, said: “Under new ownership and leadership, Poundstretcher is changing rapidly.
“The customer feedback on our price reductions and new brands has been fantastic.
“The ongoing cost of living crisis is putting a heavy burden on households across the country, so I’m pleased that we can help our customers save money. I’m also seeing more and more customers shopping with us every week.
“To mark the start of this new journey, we are giving away tens of thousands of pounds worth of vouchers across the country in one weekend.”
Fortress Investment Group, owner of Majestic Wine, Vagabond Wines and Punch Pubs Group, acquired Poundstretcher in April 2024.
Lisa Gallagher, duty manager at the Bolton store, said: “The changes at Poundstretcher have been incredibly rapid under the new management.
“My team and I are passionate about our business and it’s great that customers have noticed the lower prices and new brands in our store.
“We are excited to celebrate this new chapter with a three-day event where you can win a store voucher. We look forward to welcoming more customers into our store.”
