Online retailers are quickly adapting their operations as a result of the coronavirus disease, also known as COVID-19. Retailers are encouraging consumers to shop online as well as heavily cleaning their stores and potentially closing them.

Ecommerce sales in many product categories have already spiked, including an 817% increase in online sales in the virus category (products including hand sanitizers, gloves, masks and antibacterial sprays), an 198% increase in cold and flu products, a 152% increase in pain revilers, 186% increase in toilet paper, 69% increase in canned goods and 58% increase in shelf-stable products, according to data from Adobe Analytics, which compares February 2020 online sales data with January 2020. The research firm bases its data on more than 1 trillion visits to more than 4,500 retail sites and measures transactions from 80 of the top 100 U.S. online retailers ranked in the Top 1000.

Many retailers have communicated with their customers via email or with a message on their website about how they are adapting to the coronavirus. For example, some retailers, such as bulk-shopping grocer Boxed Wholesale (No. 339 in the 2019 Digital Commerce 360 Top 1000), have alerted shoppers that because of a surge in orders, they are wiped out of some products—like disinfectants—are putting limits on the quantities of items shoppers can buy, and shoppers may have a delay in shipments.

Luxury goods company LVMH Moët Hennessy – Louis Vuitton SE, which owns brands such as Louis Vuitton and cosmetics retailer Sephora, also joined the fight to help combat the coronavirus in France by making large quantities of hand sanitizer.  The luxury goods brand said Sunday, March 15, that three of its cosmetic facilities would begin manufacturing hydro-alcoholic gel to be delivered to French health authorities for free starting March 16. The gel will be provided for as long as necessary, according to Bloomberg.

“LVMH intends to help address the risk of a lack of product in France and enable a greater number of people to continue to take the right action to protect themselves from the spread of the virus,” LVMH said in a statement.

Most retailers are encouraging more shoppers to shop online or in their app and to take advantage of omnichannel offerings. They are also enhancing store cleaning procedures and updating sick time policies for employees. Some retailers, however, have no operations hiccups.

Here is the latest update from retailers:

Walmart Inc.: The retail giant is reducing store hours in an effort to keep stores bettee stocked. It is also encouraging shoppers to shop on Walmart.com and try buy online pick up in stores services. “Many of you are already taking advantage of these services,” the retailer wrote. “If you’re not, this could be a good time to try online delivery or our store pickup options or to use the Walmart Pay feature of our app when paying at the register.”

Target Corp.: The retailer on March 7 limited the number of items shoppers could purchase for items such as cleaning products, medicine and non-perishable food, according to its website.

With the reduced capacity across the business, our digital orders may take extra time to reach you and we appreciate your understanding and patience with our teams during this transition.” It is also offering free shipping on orders more than $40 through April 30. The retailer updated its shipping page to reflect this and does not list its previous free shipping threshhold.

Our contact centers are available to help answer any questions you might have about your experience. And our websites, Facebook and Instagram accounts are always available for inspiration—sometimes we all need a short break from the news.”
