One of Walmart’s most useful pricing tools can help sellers stay competitive with Amazon automatically—but only when it is configured correctly.
Amazon Pricing Can Become a Walmart Problem
If you sell the same products on Amazon and Walmart, pricing cannot be managed independently.
Walmart monitors external e-commerce pricing when evaluating how competitive an offer is. Its Pricing Insights dashboard specifically compares Walmart offers against similar products found on external websites.
That creates a common problem.
Your Amazon price changes from $39.99 to $34.99, while Walmart remains at $39.99.
Now your Walmart offer may appear uncompetitive against the external market. Depending on the circumstances, pricing issues can affect price competitiveness, Buy Box eligibility and, in more serious pricing-rule situations, listing visibility.
Many sellers try to manage this manually.
There is a better option.
Walmart’s Repricer Can Follow External Pricing Automatically
Walmart provides a free automated Repricer inside Seller Center.
Instead of checking Amazon every day and manually updating Walmart, sellers can create a pricing strategy that reacts to external market prices while staying within minimum and maximum prices they control.
Walmart currently offers strategies designed around:
- External prices
- Walmart Buy Box prices
- The most competitive price between the two
Walmart says the Repricer monitors Walmart.com and external sites and automatically adjusts enrolled items according to the strategy and guardrails selected by the seller.
The Important Part: Connect the Correct Amazon ASIN
This is where the setup becomes particularly useful for brands selling on both marketplaces.
For Walmart’s External Price and Competitive Price Repricer strategies, Walmart allows sellers to provide an External Product ID.
Walmart’s current documentation specifically identifies this external product ID as the 10-character Amazon ASIN.
That means you can tell Walmart which Amazon product corresponds with your Walmart SKU.
For example:
Walmart SKU: ABC-123
Amazon ASIN: B0XXXXXXXX
Now your repricing strategy has a defined external product reference instead of leaving the comparison entirely to automated product matching.
For large catalogs, that can be extremely valuable.
Why the Correct ASIN Matters
Walmart can occasionally identify the wrong comparable external product.
That creates dangerous pricing decisions.
Imagine your Walmart item is a 24-pack for $29.99, but the external comparison is mistakenly made against an Amazon 12-pack selling for $19.99.
Those aren’t comparable offers.
You don’t want an automated pricing strategy reacting to bad comparison data.
Before assigning an Amazon ASIN, verify:
- UPC/GTIN
- Pack count
- Size
- Color
- Model
- Variation
- Product configuration
Automation is only as good as the product match behind it.
Set a Minimum Price Before Turning It On
The second critical piece is your pricing floor.
Walmart allows sellers to establish minimum and maximum seller-allowed prices for Repricer items.
This should never be guessed.
Your minimum should account for:
Product cost + Walmart referral fee + fulfillment + shipping + advertising + required margin
The objective isn’t simply to match Amazon at any cost.
The objective is to remain externally competitive without allowing automation to destroy profitability.
This Can Help Prevent Pricing Problems Before They Happen
This is where we see the biggest operational advantage.
Instead of:
Amazon price changes → Walmart becomes uncompetitive → Seller notices sales declining → Team investigates → Walmart price gets changed
you can build:
Amazon/external price changes → Walmart Repricer responds within your rules
That removes a major manual step from multichannel pricing management.
Walmart’s own data shows the broader potential of Repricer. For items newly enrolled in May 2025 and monitored through June 2025, Walmart reported up to a 9% average lift in price competitiveness, 30% increase in Buy Box win rate and 40% GMV growth. Walmart notes that individual results vary based on strategy settings.
The MaxifyPPC Recommendation
For brands selling significant volume across both Amazon and Walmart, Walmart’s Repricer should not be ignored.
But don’t simply switch it on across the catalog.
For important SKUs:
1. Identify the exact corresponding Amazon ASIN.
2. Verify it is truly the same product and variation.
3. Calculate your minimum profitable Walmart price.
4. Choose the appropriate External Price or Competitive Price strategy.
5. Monitor Pricing Insights to confirm the item remains competitive and profitable.
Done correctly, Walmart’s Repricer isn’t simply a Buy Box tool.
It can become part of your cross-marketplace pricing infrastructure—helping Walmart pricing react to external competition without requiring someone to manually monitor Amazon every day.
Final Thoughts
If you’re selling the same catalog on Amazon and Walmart, your pricing teams cannot operate in two separate worlds.
A price change on Amazon can affect how competitive Walmart views the same product.
Walmart already gives sellers the technology to automate much of this.
Use the Repricer. Connect the correct external product. Set intelligent pricing floors. Then monitor the results.
The goal isn’t to always have the lowest price.
The goal is to stay competitive without sacrificing profitability—or discovering a Walmart pricing problem after the sales have already disappeared.
