Below are the latest changes at some of the most prominent supermarket chains.
All Target stores will reserve the first hour of shopping on Wednesdays for "vulnerable guests — including elderly and those with underlying health concerns." The company is encouraging others to shop outside of that time.
The retailer is also cutting its opening hours, closing all stores at 9 p.m. local time and is enforcing limits on how many items of particularly high-demand products one shopper can buy.
The retailer is "strongly encouraging" shoppers who are not considered high-risk to avoid visiting stores during the first hour of opening, reserving that time for seniors. Dollar General also will close all stores an hour early every day for cleaning, restocking and to give workers a bit of a break.
The largest U.S. retailer is adding a "senior hour" to every Tuesday from March 24 to April 28. This applies to customers 60 and older, who will have exclusive access to Walmart stores and pharmacies for an hour before official opening time, which in many cases will mean 6 a.m. to 7 a.m.
Walmart says it's temporarily closing Auto Care Centers and imposing per-person restrictions on paper products, milk, eggs, cleaning supplies, hand sanitizer, water, diapers, wipes, formula and baby food.
Stop & Shop
The stores are opening early to allow people over 60 and with weakened immune systems to shop from 6 a.m. to 7:30 a.m. The supermarkets will have shorter hours, opening from 7:30 a.m. to 8 p.m. The company is also limiting per-person purchases of some cleaning and sanitizing products, encouraging shoppers to "buy just what you need."
The supermarkets owned by Albertsons plan to reserve every Tuesday and Thursday from 7 a.m. to 9 a.m. for vulnerable shoppers, including seniors, pregnant women and people with compromised immune systems.
The company is also "asking customers to respect quantity limits of select, high-demand items (like hand sanitizers and household cleaners) to help ensure more of our neighbors can find the products they need."
Amazon's retail chain is offering the hour before each store's official opening time for people 60 and older. Whole Foods also says its locations will close to shoppers "up to two hours early," though they will remain open for pickup and Amazon Prime delivery.
Many retailers and malls also are restricting their hours or temporarily closing. Trade publication Retail Dive is keeping a handy running list here.
