What Is the Buy Box on Amazon?
The Amazon Buy Box is the section on a product page where shoppers can quickly click “Add to Cart” or “Buy Now”. It looks simple—but it’s a big deal for sellers since it controls the majority of sales on Amazon.
If multiple sellers offer the same product, Amazon chooses which one gets featured in the Buy Box. Winning it means your offer is the one customers see first—and most people never scroll past it.
Whether you're selling or just curious how Amazon works behind the scenes, understanding the Buy Box helps explain why some sellers thrive while others struggle to get noticed. That is why in this guide, we will explain the basics of it for you to understand it better.
Key Takeaways:
- The Buy Box is the white section on Amazon product pages where customers click to purchase items from the winning seller
- Amazon's algorithm selects Buy Box winners based on price, shipping speed, seller performance, and inventory availability
- Winning the Buy Box is essential for seller success since most Amazon purchases happen through this feature
Where Does the Buy Box Appear on an Amazon Page?
On desktop, the Buy Box appears on the right side of an Amazon product page. On mobile, it shows up lower on the screen to fit the layout. It’s the white box that contains the main “Add to Cart” and “Buy Now” buttons.
This section is where most purchases happen. It highlights one seller’s offer, making it quick for customers to buy without comparing every option.
What you’ll usually see inside the Buy Box:
- Product price and shipping details
- Seller’s name and rating
- Prime eligibility
- Add to Cart button
- Buy Now button (if available)
When you tap “Add to Cart,” the item goes straight into your shopping cart. The “Buy Now” option lets you skip the cart and check out immediately.
Even if multiple sellers offer the same item, only one can control the Buy Box at a time. Amazon picks the seller based on price, shipping speed, customer service, and availability.
Why the Buy Box Is Important?
It is essential since more than 80% of Amazon sales happen through the Buy Box. If your offer isn’t in it, most shoppers won’t see it—let alone buy it. Here's how it can affect you store:
Massive Sales Impact
Winning the Buy Box means your product is the default option. Shoppers can add it to their cart or buy it instantly, with just one click. If you don’t have the Buy Box, your listing shows up under “Other Sellers,” which few customers bother to check.
More Visibility and Trust
The Buy Box appears in a bright, easy-to-spot section on the product page. It highlights your price, shipping speed, and Prime eligibility. Amazon’s algorithm chooses Buy Box winners based on seller performance—so customers often assume your offer is the best.
Higher Conversion Rates
The Buy Box simplifies the buying process. It removes decision fatigue by showing only one seller—so shoppers are more likely to complete the purchase quickly.
Competitive Advantage
| With Buy Box | Without Buy Box |
|---|---|
| 80%+ of sales | Low visibility |
| Prime placement | Buried under other offers |
| One-click purchase | Multiple steps required |
Losing the Buy Box means losing sales. Your listing might still exist—but for most customers, it’s invisible.
How Does the Amazon Buy Box Work?
The Buy Box chooses one seller to feature based on price, shipping, and seller performance—and this choice can change throughout the day.
When multiple sellers offer the same product, Amazon doesn’t just show them all. Instead, it uses a real-time algorithm to decide who gets the Buy Box.
Here’s what happens:
- Amazon checks which sellers are eligible based on account health and fulfillment method.
- It compares offers using factors like pricing, delivery speed, and customer service.
- The best-performing seller gets featured in the Buy Box—but not always for long.
- The algorithm runs constantly, so different sellers can win the Buy Box at different times.
Types of Buy Box Rotation
| Simple Rotation | Complex Rotation |
|---|---|
| Shared among top-performing sellers | Focus shifts more heavily to price |
| Rotates regularly based on performance metrics | Can trigger aggressive price competition |
Your Buy Box share depends on how you stack up against other sellers at any moment. Consistently strong performance helps you win—and keep—that top spot.
What Makes a Seller Eligible for the Amazon Buy Box?
To qualify for the Buy Box, you need a Professional Seller account and strong performance across pricing, shipping, and customer service metrics.
Amazon only lets certain sellers compete for the Buy Box. These sellers must meet strict criteria across multiple areas.
Requirements for Buy Box Eligibility
1. Professional Seller Account
Only Professional accounts can win the Buy Box. Individual accounts are excluded, no matter their performance.
2. Competitive Total Price (Item + Shipping)
Amazon favors offers that match or beat prices found on other major retail sites. Make sure your total cost is competitive—not just the item price.
3. Fulfillment Method
Using Fulfillment by Amazon (FBA) can give you an edge. Amazon trusts its own network for fast, reliable delivery. FBM (Fulfilled by Merchant) sellers need excellent logistics to compete.
4. Fast and Reliable Shipping
Speed matters. The faster and more predictable your shipping, the better your chances of winning the Buy Box.
5. Strong Seller Performance Metrics
Maintain these benchmark targets:
- Order Defect Rate: under 1%
- Late Shipment Rate: under 4%
- Cancellation Rate: under 2.5%
- Valid Tracking Rate: over 95%
6. Consistent Inventory Availability
Running out of stock can immediately remove you from Buy Box rotation. Keep inventory levels steady.
7. Positive Seller Feedback
Higher ratings and strong account health improve Amazon’s trust in your service quality. Good feedback also signals reliability to customers.
Common Myths About the Amazon Buy Box — And What’s Actually True
There’s a lot of bad advice about how the Buy Box works. Let’s clear it up with facts.
Myth 1: Lowest price always win the Buy Box
No. Price is just one factor. Amazon also looks at seller performance, shipping speed, customer service, and fulfillment method. A slightly higher price with faster delivery or better ratings can win.
Myth 2: Only big sellers get the Buy Box
Not true. Small and new sellers can win the Buy Box if they meet Amazon’s performance standards. Order defect rate, shipping reliability, and account health matter more than sales volume.
Myth 3: Once you win the Buy Box, you keep it.
Not necessarily. The Buy Box rotates between sellers based on real-time performance. You can lose it if your metrics slip or your competitor improves their offer.
Myth 4: You must use Fulfillment by Amazon (FBA)
No, but it helps. Fulfillment by Amazon often improves your chances, but merchant-fulfilled sellers (FBM) can win if they offer fast, reliable shipping and maintain excellent metrics.
Myth 5: More reviews = better Buy Box chances
Quality matters more than quantity. Recent, positive reviews carry more weight than old ones. A seller with fewer—but better—recent reviews can outperform one with a massive but outdated review history.
Final Thoughts
The Buy Box might look like a small part of an Amazon listing, but for sellers, it can make or break their business. Winning it means visibility, trust, and most importantly—sales.
If you’re serious about selling on Amazon, understanding how the Buy Box works is essential. From pricing strategy to shipping speed and account health, every detail matters. And while there’s no one-size-fits-all trick to guarantee it, sellers who consistently deliver value and strong performance have the best shot.
Bottom line? The Buy Box isn’t just a feature—it’s a key part of how Amazon decides who gets seen and who gets ignored.

Frequently Asked Questions
1. How do I know if I have the Buy Box?
You have the Buy Box if your offer appears as the default seller on the product page with the "Add to Cart" or "Buy Now" button.
You can also check this in your Amazon Seller Central account under the “Manage Inventory” page. If it shows “Buy Box Eligible” and you’re the one currently featured, you’re winning it.
2. Why am I not winning the Buy Box?
You may not win the Buy Box if your price is too high, your shipping is slow, or your seller metrics are low.
Amazon compares your offer with others. If your performance (like delivery time, price, or feedback) is weaker, another seller may win instead.
3. Is the Buy Box available for all listings?
No, not all listings are eligible for the Buy Box. Only professional sellers with good account health can compete.
Some categories, product conditions (like used), or listings with no competition may not show a Buy Box at all.
4. Can more than one seller share the Buy Box?
Yes, Amazon rotates the Buy Box between sellers with similar performance and prices.
This means even if you're not the only seller, you can still win the Buy Box at different times depending on your metrics and offer.
5. What metrics affect Buy Box eligibility the most?
Key metrics include Order Defect Rate (<1%), Late Shipment Rate (<4%), Cancellation Rate (<2.5%), Valid Tracking Rate (>95%), and seller feedback.
6. How does Amazon decide who gets the Buy Box?
Amazon chooses the Buy Box winner based on price, shipping speed, seller ratings, and account health.
Even small differences in performance can affect who wins. Amazon wants to show the best offer for the customer—not just the lowest price.
7. Does price affect your chances of winning the Buy Box?
Yes, offering a competitive price—especially with shipping included—can help you win the Buy Box.
But price isn't everything. Amazon also looks at delivery time, seller ratings, and fulfillment method (FBA vs FBM).
8. Can new sellers win the Buy Box?
Yes, new sellers can win the Buy Box, but they must use a professional account and have good metrics.
Amazon may require some selling history before giving access. Using FBA and offering great service helps build trust faster.
9. What’s the impact of losing the Buy Box on sales?
Losing the Buy Box can lead to fewer sales because most buyers use the default “Buy Now” button.
Even if your product is still listed, being outside the Buy Box means shoppers have to dig to find your offer.
10. How often does the Buy Box winner change?
The Buy Box can change many times a day based on pricing, shipping, and seller performance.
Amazon updates it in real time, so small changes to your offer—or your competitor’s—can affect who’s shown.
