"Should I sell on Walmart too?" comes up constantly among Amazon sellers looking for a second channel, and the honest answer is that it depends on how much operational overhead you're willing to absorb for what is, in most categories, a meaningfully smaller pool of traffic than Amazon. That doesn't mean it's not worth it โ€” it means the decision needs a clearer framework than "more channels equals more sales."

Traffic and Demand Reality

Amazon remains the default starting point for product search for a large share of U.S. online shoppers, and Walmart Marketplace, while genuinely large, sits behind it in both total traffic and typical conversion intent for most third-party categories. That doesn't make Walmart a bad channel โ€” it makes it an additive one. Sellers who treat Walmart as a replacement for Amazon effort are usually disappointed; sellers who treat it as incremental revenue on top of an already-working catalog tend to be satisfied with the results.

Competition Differs by Category

Because fewer third-party sellers list on Walmart Marketplace than on Amazon, well-optimized listings in under-saturated categories can rank and convert more easily than the same listing would on Amazon, where competition is often fiercer. This is category-dependent โ€” some verticals on Walmart are just as competitive as Amazon โ€” but it's a real advantage in the categories where it applies.

Operational Overhead of Running Both

  • Separate seller accounts, separate performance metrics, and separate policies to track and stay compliant with
  • Inventory sync becomes non-negotiable โ€” overselling on one channel because stock wasn't updated from the other is one of the most common multichannel mistakes
  • Content has to be adapted, not just copy-pasted โ€” titles, images, and attributes that rank well on Amazon don't always map cleanly onto Walmart's listing requirements
  • Customer service and returns workflows effectively double, since each platform has its own rules and response-time expectations

Fee Structures Aren't Identical

Referral fee rates by category are broadly similar in range between the two platforms, but fulfillment costs, storage fees, and advertising costs don't map one-to-one, so a product that's profitable on Amazon isn't automatically profitable on Walmart at the same price point. Running the margin math per channel, rather than assuming your Amazon numbers translate, avoids an unpleasant surprise after a few months of Walmart sales.

Brand and Pricing Consistency

Selling on both platforms raises the question of price parity โ€” Amazon has historically been sensitive to sellers listing lower prices elsewhere, and inconsistent pricing across channels can also confuse repeat customers who shop on both. Deciding on a pricing policy across channels before you launch on Walmart avoids having to unwind an awkward pricing gap later.

Who Should Actually Add Walmart

Walmart tends to make the most sense for sellers who already have a stable, profitable Amazon operation and the bandwidth to run a second channel properly โ€” not as a rescue plan for an underperforming Amazon business. If your current operation is stretched thin managing one marketplace well, a second one usually multiplies the strain rather than the revenue. If you have the capacity, the incremental sales and reduced platform-concentration risk are genuinely valuable.
