Some Corpus Christi area grocery stores are limiting products amid the growing concern over the coronavirus, and some began limiting hours on Saturday.

On Saturday, H-E-B stores announced all stores will open at 8 a.m. and close at 8 p.m. until further notice as of Sunday, March 15. The temporary change in store hours will allow H-E-B to "better restock shelves" for its customers.

H-E-B customers can also expect reduced services at the deli, bakery and floral departments, according to a news release.

On the same day, Walmart stores announced its stores will open at 6 a.m. and close at 11 p.m. until further notice as of Sunday, March 15. The 24-hour supermarket's decision to reduce hours will help "ensure associates can clean and stock products." Stores operating under more reduced hours will keep current hours of operation.

H-E-B is among the stores setting limits on disinfectant products and water.

Signs were posted at H-E-B and Sam's Club stores Thursday alerting shoppers of the limits.

On Tuesday, Walmart issued a statement saying stores would continue to restock cleaning items as quickly as possible.

"We are working to replenish those items quickly, including diverting products to areas of the country where they are needed most and routing deliveries directly to stores," Walmart said in a statement. "We have also authorized our store managers to manage their inventory, including the discretion to limit sales quantities on items that are in unusually high demand."

As of 4:20 p.m. Thursday, there were no limits at Walmart on Saratoga Boulevard. The Staples Street location is limiting to two cases of water per customer. The Greenwood Drive location set limits of four cases of water and four cleaning supply items per customer.

Sam's has put a limit in effect of two cases of water per customer.

Photos on social media show shelves for toilet paper were empty at H-E-B Plus! on Saratoga Boulevard, one of the more high traffic locations in the city.

The Walmart on Saratoga Boulevard will open its store at 6 a.m. for guests 60 and older. The pharmacy will also be open for pick up or drop off.
