Home Bargains is set to open a new store in St John's Retail Park next month.
The standalone retailer's move to Rope Walk will create between 65 and 75 new jobs.
Emily Randall Bowen, Home Bargains assistant manager, said: "We can’t wait to welcome and see you all."
TJ Morris Ltd, trading as Home Bargains, has been ranked 6th in the Which? list of top 100 stores - tied with Apple stores - making it the highest ranking discount retailer in the UK.
The new store opens on October 17.
