Grocery stores, city leaders ask public to not 'panic buy'

To combat empty shelves at grocery stores, Texas Gov. Greg Abbott is waiving some trucking regulations to help expedite delivery of resources around Texas.

H-E-B and Kroger have asked the public to keep calm and to not buy more than what is needed.

"H-E-B has been preparing for coronavirus for several months and we are in a strong position to keep replenishing our shelves. Customers should not panic, we have the ability to restock shelves and encourage our customers to remain calm. H-E-B Partners are ready to help Texas slow the spread," the grocery chain said in a statement.

H-E-B also tweeted its customers, asking them to "leave some" behind for others: "We encourage preparedness, not stockpiling – please buy what you need & leave some for your neighbor behind you."

Kroger is sharing a similar message with its customers, reminding shoppers the grocer has been working around-the-clock to keep store shelves stocked.

The store activated its preparedness plan several weeks ago and continues to work closely with its vendors to keep supplies replenished, according to a statement.
