The chain will open in the former Toys R Us unit at Fife Central Retail Park at 9am on September 27.
And a spokesman said it has no plans to close the current store on the High Street.
The shop is expected to sell a wide variety of branded products including toys, food and drink, pet range, health and beauty and homeware.
A spokesperson from B&M said: “We’re feeling really positive about the creation of even more jobs for local people and we hope customers are going to be delighted with their new store.
“We are all really excited to get the doors open and welcome our new customers through the door in a few weeks.”
Job roles are currently advertised on the B&M careers website and range from sales assistants to floor managers and cleaners.
