Sam’s Club has announced that it is making changes to its store hours during the coronavirus outbreak. The wholesale retailer is now open from 9 a.m. to 8 p.m., Monday through Saturday, and 10 a.m. to 6 p.m. on Sunday.

The decision to change its hours will allow employees time to restock shelves and clean stores. The company is still allowing for curbside pickup orders, starting at 7 a.m.

On Tuesdays and Thursdays at all stores nationwide, Sam’s Club has dedicated special shopping hours from 7 a.m. to 9 a.m. for seniors and those with disabilities or compromised immune systems. Sam’s Club’s Pharmacy and Optical Centers will also be open during this time.

Starting on Thursday, Sam’s Club Optical Centers will be open from 10 a.m. to 2 p.m., except during the specially designated hours on Tuesday and Thursday, when they will be open from 7 a.m. to 2 p.m. Optical Centers will only provide essential services such as repairing glasses and order pickups.

Sam’s Club has temporarily closed its Tire & Battery Centers but is still honoring all existing appointments and tire orders. The company said it will continue to sell tires, batteries, and wiper blades on a carryout basis with no installation.

For customers looking to place curbside pickup orders, Sam’s Club has reduced the order ahead time from five days to one day with new time slots opening every morning. But the company said that some customers may experience order delays, cancellations, or higher wait times during pickup, which will be communicated via email, text message, website, or mobile app.

Vulnerable customers may also use Sam’s Club Scan & Go check out service without leaving their cars from 7 a.m. to 9 a.m., while workers grab the items they placed on their list.

Sam’s Club said it is limiting some high-demand items to one per customer to ensure that more consumers have access to these essential products.
