DoorDash Inc., the biggest food delivery app in the U.S., will start delivering goods from 7-Eleven, Wawa and other convenience stores to Americans who are mostly stuck at home for the foreseeable future.

The San Francisco-based startup said it began testing the sale of paper towels and other packaged goods this year and decided to accelerate the rollout due to the coronavirus pandemic. DoorDash has more than 1,800 convenience stores around the U.S. available on the app, the company said.

The new offering competes to some extent with Amazon.com Inc.’s grocery delivery service and Instacart Inc. Both companies have struggled to meet demand since the outbreak and have said they’re adding a combined 400,000 workers. This week, some workers at both companies went on strike over accusations of unfair pay and labor policies.

Uber Technologies Inc. is also looking to expand its food delivery app with groceries. It owns a majority stake in Latin America’s Cornershop and intends to bring the grocery service to other countries. “That business is absolutely exploding in the right way,” Dara Khosrowshahi, Uber’s chief executive officer, said in a Bloomberg TV interview last month. “We have a global brand, and we can essentially take Cornershop and make it a global brand.”
