When the pandemic forced Dick’s Sporting Goods to close its hundreds of stores in March, the retailer hustled to set up curbside pickup within two days. Its initial attempt, though, was just this side of a children’s lemonade stand.

“When you drove up, there was a sign in the window with a phone number, and people used the landline to call the stores and they’d deliver it out,” Lauren Hobart, president of Dick’s, said of the “very scrappy” operation. Email and text alerts would come later.

Scrappy or not, curbside pickup not only rescued Dick’s sales during the lockdowns, it has also emerged as many retailers’ best strategy for long-term survival in the e-commerce age. And what started as a coronavirus stopgap is likely to have a permanent impact on the way people shop, along with giving them a new reason to continue to visit beleaguered physical stores.

The popularity of curbside pickup reveals that the future of retail is not just more packages piling up on people’s doorsteps. Beyond satisfying the need for contactless shopping in the pandemic, it taps into Americans’ desire to drive to a store, a pull that can be just as strong as, or even stronger than, the convenience of home delivery.

“Americans are used to their cars and actually do like stores, so this is kind of a hybrid where you’re getting the best of both worlds,” said Oliver Chen, a retail analyst at Cowen.

As of August, about three-fourths of the top 50 store-based retailers in the United States offered curbside pickup, according to Coresight Research, an advisory and research firm that specializes in retail and technology. Anything from a sweater to a book is now as easy to pick up as a sandwich.

Target said its curbside sales grew more than 700 percent in the last quarter, while Best Buy reported nearly $5 billion in online revenue in the second quarter, a company record, and said 41 percent of that had come from curbside or in-store pickup.

The rise in curbside pickup, part of a larger surge in e-commerce sales, has implications for preserving retail jobs, though workers’ duties are likely to transform. It is also helping to keep brick-and-mortar spaces relevant when thousands of storefronts have emptied out as more customers move online.

Curbside allows certain big-box retailers to convert their stores into mini e-commerce fulfillment centers, while avoiding the money-losing step of shipping goods to homes.

By driving to the store to pick up an online order, “the customer takes the last mile,” Mr. Chen said, referring to the typically expensive final step in package deliveries.

The rising popularity of curbside coincided with Amazon’s struggles with its vaunted supply chain and usually seamless home delivery system in the early months of the pandemic. As people rushed to place orders for everything from toilet paper to backyard swimming pools, Amazon dealt with out-of-stock items, price gouging and delayed or inaccurate shipments.

That was a boon for chains like Dick’s, Best Buy, Target and Walmart, which harnessed the merchandise in their thousands of stores to new effect especially as summer began.

“Amazon struggled a bit at the beginning like everybody did, because, boom, when the demand came, it was so great it hit the whole system and kind of overwhelmed it,” said Walter Robb, a former co-chief executive of Whole Foods and executive-in-residence at S2G Ventures, a venture fund focused on food. “Those that have been able to be agile on their feet with these digital offerings have made some gains.”

But nowhere is the shift more significant than at big-box chains that also sell groceries. The 700 percent growth in Target’s Drive Up offering has spurred the chain to add fresh and frozen groceries to the service and create up to 12 additional parking spaces for pickup at stores. It has announced plans to double the number of store employees dedicated to in-store and curbside pickup services during this holiday season. The retailer has even included product samples in orders.
