While Bi-Lo and Harris Teeter were busy moving into former Piggly Wiggly stores, Food Lion had a few updates of its own in the works.

The grocery chain based in Salisbury, N.C. will debut some new offerings at its stores in the Charleston market on Wednesday. To celebrate the improvements, Food Lion will give away a free bag of groceries to the first 50 customers in the store every day through Saturday.

The grocery store has lowered prices on 6,000 items including My Essentials, Food Lion’s brand of goods. Kiosks called MVP Savings Centers have been added to the stores so customers can redeem personalized offers while they shop.

The company also improved its selection of produce, and they’re backing its freshness with a bold guarantee. If customers aren’t satisfied with their produce purchases, the store will give them twice their money back.

The updates apply to 169 stores mostly in Charleston, Columbia, Myrtle Beach, Greenville, N.C., and Wilmington, N.C. The company added 500 employees to their work forces in those markets to improve customer service. About 66 were hired in the Charleston area.

“We’re really trying to improve our service. All of this is based on customer feedback,” said Benny Smith, a Food Lion spokesman.

Food Lion will also donate $2,000 to food banks in the five communities with updated stores.

Billy Harcum, the director of operations for the Charleston market, will present a $2,000 check to the Lowcountry Food Bank on behalf of Food Lion at 11 a.m. Wednesday at the store at 5500 Dorchester Road.
