Thirty new jobs are to be created with the relocation of Marks and Spencer's Simply Food store on Belfast's Lisburn Road to larger premises across the road.
The new shop will move to the site of the former Co-op and will open its doors on Wednesday, July 9.
More than 5,000 lines of food and drinks will be available at the 11,000 sq ft store along with a cafe, catering for up to 50 people.
Store manager Conor McLoughlin said the new premises would "provide a much bigger and better shopping experience for local people, with the added bonus of 70 car-parking spaces.
"With a wide selection of M&S food and wine, combined with extended opening hours, we hope that customers will join us on July 9 to see all of the new and exciting features that we will be bringing to the area."
When the intended move was revealed last September, there were concerns that the post office located at the Co-op could be lost or jeopardised, however, in March, a new one opened just 100 metres away at the nearby Mace store.
