Batteries, cold medicine, and that forgotten dinner ingredient are now just a tap away. Amazon, Walmart, and their rivals have pulled online a category of purchase that e-commerce could never touch before: those indispensable things shoppers once had to get in the car to buy. The orders are small, urgent, and single-item, and the companies processing them are only beginning to reckon with whether these tiny purchases can ever pay for themselves.

Walmart says customers who see its fastest delivery option increasingly reach for it the moment a household runs short, grabbing cold medicine when a fever hits, coffee pods when the tin runs dry, or the one ingredient a recipe still needs. That impulse looks nothing like the planned, bulk-ordered purchases that built e-commerce over two decades, where a shopper filled a cart, waited days, and treated shipping as the cost of avoiding a store trip.

What changed is the delivery window, because a purchase this small and this immediate was never worth putting online until the wait shrank from two days to 30 minutes.

In India, where quick commerce is years ahead of the U.S., groceries and staples took 61.33% of the market in 2025, with fresh produce, dairy, and snacks close behind, according to global market research firm Mordor Intelligence. It attributes that lead to households running out of those daily-use items constantly, and it's those households, restocking the same handful of staples again and again, that place the frequent, small orders that define the format.

The trouble is that these small orders are hard to deliver profitably. A Grant Thornton Bharat survey of more than 1,500 quick-commerce users in India found the average basket worth roughly 400 rupees, or $4.17, against which the last-mile delivery cost of 35 to 45 rupees per order swallowed 50% to 70% of the gross margin. The margin on a typical order runs just 50 to 60 rupees, a cushion so thin that a slightly smaller order or a single refund can eat into the entire cost benefit.

The cushion depends entirely on keeping the rider busy. To earn about 1,000 rupees a day, a single rider has to complete roughly 30 trips, so every drop that goes wrong not only erases one order's 50-to-60-rupee margin but also wastes a slot the rider needed to fill to make the day pay.

Botched deliveries threaten the arithmetic. Almost 40% of the Grant Thornton respondents named late delivery as their biggest complaint, and each late drop that triggers a refund pulls a whole order underwater. The pressure is pushing platforms away from their most aggressive speed marketing. In India, where customers gravitated to the sub-10-minute promise for 62% of orders in 2025, companies are shifting the consumer promise toward wider 8-to-30-minute windows, according to Mordor Intelligence. A slightly longer window lets a platform load riders with more categories per trip and combine deliveries.

Fees and memberships offsetting the unprofitable delivery

If slowing down is one way to make the small order work, charging for it is another, and Amazon has built its answer to the problem directly into its pricing.

Prime members pay $3.99 per Amazon Now order, an on-demand purchase delivered in 30 minutes or less, and anyone ordering less than $15 of goods pays an extra $1.99 surcharge. Non-Prime customers pay far more — $13.99 per delivery plus a $3.99 surcharge under $15 — which turns the fee structure itself into a nudge toward membership.

Rather than absorb the cost of these orders alone, retailers have turned the small order into a tool for acquiring customers. "Speed isn't simply a fulfillment metric. It's an acquisition strategy," Walmart U.S. CEO John Furner argued in the company's most recent earnings call. And the customers it acquires are worth chasing at a loss, because, as CFO John David Rainey told investors, "our members spend approximately four times more than nonmembers." The 30-minute delivery, in other words, is bait for a shopper who will later buy far more.

Setting aside claims, Rainey said Walmart's advertising, membership, and marketplace divisions generated half of its added profit in the second quarter of fiscal 2026, pointing to the higher-margin businesses that fast delivery funnels customers into. The delivery itself may barely break even, but it feeds shoppers toward the businesses that do the earning.

Walmart's stores are what make the model work, because they double as fulfillment nodes already stocked with food, medicine, and household goods within a short drive of most of the country. The company now uses its stores as the last-mile fulfillment point for 80% of its e-commerce orders and 100% of its fast deliveries, Furner told investors. U.S. fast-delivery volume grew 48% in a single quarter, and fee-based fast deliveries reached a record 37% of store-fulfilled orders.

DoorDash's numbers show the same trade running in the opposite direction. Total orders rose 19% to 685 million in the fourth quarter of 2024, and DoorDash counted a record of more than 42 million monthly active users that December, climbing from more than 37 million a year earlier. More customers ordered more often from grocery and other non-restaurant categories the company had newly added.

More people ordering more frequently is the whole point. The size of any single order matters less if the same customer comes back three times a week.

The bet across all of these companies is that frequency, fees, and adjacent margin can eventually outrun the cost of the delivery itself. Walmart has just been unusually explicit about it. Doug McMillon, who served as president and CEO of Walmart from February 2014 to January 2026, had told investors the company's newer digital business "over time can be more profitable than the first P&L and lift the total," meaning the delivery and e-commerce operation could one day earn more than the stores that built the company.
