A shopper needs a product. They open Amazon out of habit and see next-day delivery. Then, almost as a reflex, they check Walmart. Same product, comparable price, but it can arrive this afternoon. They buy it there.
Nothing about the brand changed. The price barely moved. What changed was the convenience each platform offered in that specific moment. And that small, ordinary decision points at a much bigger question for anyone selling online: if the product and price are comparable, what actually decides where a customer buys?
For brands weighing Amazon versus Walmart, or whether to add a marketplace at all, that is the question worth answering. Not which platform is better in the abstract, but what role each one plays in a real customer’s decision. This article works through that, using the delivery race between Amazon and Walmart as the way in.
Why does the same shopper choose different marketplaces for the same product?
The same shopper chooses different marketplaces for the same product because channel preference is contextual, not fixed. A person is not loyal to Amazon, Walmart, or a brand’s own site in a permanent way. Their choice shifts with the situation: how urgently they need the item, whether it is in stock nearby, what shipping looks like, whether they have a membership, how much they trust the returns process, and what kind of product it is.
That is why the same customer can behave like three different buyers in a single week. The purchase that has to arrive today goes one way. The considered, compare-the-reviews purchase goes another. The one where they want the full brand experience goes a third. The brand did not win or lose based on identity. It won or lost based on fit with the moment.
This is the shift from asking which marketplace is better to asking what job each marketplace does for your customer. It is the same journey-first thinking we covered in Rethinking Omnichannel: How the 2026 Customer Actually Decides, applied to the specific question of where a purchase lands.
Why is Walmart’s physical footprint now an ecommerce asset?
Walmart’s ecommerce advantage starts with something decidedly physical. Roughly 90% of the US population lives within 10 miles of a Walmart store or Sam’s Club, which means the company already has inventory positioned remarkably close to most of the country.
That proximity translates into speed. Walmart reports that its same-day delivery reaches 95% of US households, and that it can reach that same 95% with delivery in three hours or less (Walmart). The store network is what makes that possible. A store is no longer only a place to shop. It can also be the last fulfillment node before an online order reaches the customer.
And this is not a fringe experiment. In Q1 FY27, Walmart’s US ecommerce grew 26%, it described its own stores as digital fulfillment nodes, and more than 36% of its store-fulfilled delivery orders arrived in under three hours (Walmart). Walmart is not trying to rebuild Amazon’s infrastructure. It is turning the infrastructure it already has into an ecommerce engine.
Is Walmart actually faster than Amazon now?
Not in any universal sense, and that framing misses what is actually happening. The more accurate story is that Amazon and Walmart are both racing toward immediacy, and they are getting there through very different physical infrastructures.
Amazon is moving aggressively on exactly the everyday, frequent purchases where Walmart traditionally had the edge. In 2025, US Prime members received more than 8 billion items same-day or next-day, up more than 30% year over year, and about half of those were groceries and everyday essentials (Amazon). In 2026, Amazon rolled out Amazon Now, delivering groceries and essentials in roughly 30 minutes or less to millions of US customers (Amazon).
Amazon also still owns things Walmart does not automatically replicate: an enormous assortment with more than 300 million Prime-eligible products, a deeply installed shopping habit, and a search-and-compare experience shoppers default to. So the honest picture is a trade-off, not a winner. Amazon’s strength is breadth of assortment, purchasing habit, and the Prime ecosystem. Walmart’s strength is proximity, locally available inventory, and physical-digital integration. Both are competing to put inventory closer to the customer, because proximity to inventory is becoming part of the customer experience itself.
How does the same customer use Amazon, Walmart, and DTC differently?
The clearest way to see this is through the job each channel does in a real purchase. These are illustrative, not rules every shopper follows, but they map to how people actually behave.
On Amazon, the mindset is often: I know roughly what I want, so let me search, compare, read reviews, and get it quickly. Amazon wins the considered purchase and the habitual one.
On Walmart, the mindset is closer to: I need this today, and there is inventory near me. Walmart wins on immediacy and on the trip that blends online and store.
On a brand’s own DTC site, the mindset is: I want the full brand experience, the complete assortment, a bundle, a loyalty benefit, or something exclusive. DTC wins the relationship and the margin.
The important point underneath these scenarios is this. The question is not whether your Amazon customer, your Walmart customer, and your DTC customer are three different people. Sometimes they are the same person in three different buying situations. Marketplace preference is not always brand preference. Sometimes it is simply convenience preference.
Does being on more marketplaces automatically mean more growth?
No. Being present on more marketplaces only creates value when each channel has a clear role in the customer journey. Adding a channel because a brand feels it should be everywhere is how growth turns into overhead.
Every additional marketplace carries real weight: inventory allocation, content, pricing discipline, advertising, fulfillment, review building, operations, and margin management. A new logo in the distribution strategy is not free, and GMV without contribution margin does not solve much. Channel expansion should solve a customer or business problem, not simply increase the number of places a brand appears.
This is the discipline of intentional presence over maximum presence, and it is the same principle behind entering any new market deliberately rather than reflexively, which we work through with brands in Market Entry.
How should a brand decide which marketplaces to sell on?
A brand should decide based on the role a channel would play, not on its raw traffic. Five questions turn that from an opinion into a decision. We run through these with brands before recommending any channel expansion.
| The Question | Why It Matters |
| Is your customer already shopping there? | Platform traffic is not the same as your customer being there with intent for your category. |
| Why would they buy your product there specifically? | Delivery, price, convenience, trust, or discovery. If nothing is clearly better, the channel adds noise, not sales. |
| Can your margins support that channel? | Revenue that does not carry contribution margin creates work without building the business. |
| Can you execute it properly? | Inventory, content, advertising, and customer experience all have to hold up, or the channel underperforms. |
| What role does it play relative to the others? | Discovery, conversion, urgency, retention, or scale. Each channel should do a job the others do not. |
If a channel cannot answer these clearly, it probably is not ready to earn the investment. Being on Walmart, or Amazon, or anywhere else is a decision that should follow the customer and the economics, not the fear of missing out.
Frequently asked questions
Should my brand sell on both Amazon and Walmart?
Only if each one plays a distinct role for your customer. Amazon tends to win considered and habitual purchases through assortment and the Prime habit, while Walmart wins on immediacy and locally available inventory. If your customer shops both with intent for your category and your margins support both, running both can make sense. If one is just a second logo with no clear job, it adds cost without adding strategy.
Is Walmart delivery faster than Amazon?
Not universally. Walmart uses its store network to reach 95% of US households with same-day or three-hour delivery, while Amazon delivered more than 8 billion items same-day or next-day in the US in 2025 and now offers roughly 30-minute delivery through Amazon Now in many cities. Both are racing toward immediacy using different infrastructure, so speed depends on the product, the location, and the moment rather than one platform always winning.
Does being on more marketplaces mean more growth?
No. More marketplaces mean more growth only when each channel solves a real customer or business problem. Every added channel brings inventory, content, pricing, advertising, and fulfillment work, so expansion without a clear role tends to create overhead rather than durable growth. The goal is intentional presence, not maximum presence.
How do I choose which marketplace to sell on?
Decide based on the role the channel would play, not its raw traffic. Ask whether your customer already shops there with intent, why they would buy your product there specifically, whether your margins support it, whether you can execute it well, and what job it does relative to your other channels. A channel that cannot answer those clearly is usually not ready for investment yet.
Intentional presence beats maximum presence
The delivery race between Amazon and Walmart is a useful window into a bigger truth. Consumers do not have a single preferred ecommerce channel for every purchase. They have a preferred channel for a particular need, product, and moment. The same person buys the same product in different places for different reasons, and none of those reasons is disloyalty to the brand.
For brands, that reframes the whole marketplace question. The goal is not maximum presence across every platform. It is intentional presence, where each channel earns its place by doing a job the others cannot. That is strategy before execution, and it is how our Growth Team approaches channel decisions with the brands we work with.
