Beat Buy Box
What it does
Beat Buy Box sets your price just below whoever currently has the Buy Box — not the lowest price overall.
What's the Buy Box? The “Add to Cart” button on an Amazon listing. About 83% of sales go through it. Winning the Buy Box is the single most important factor in Amazon sales. Multiple sellers compete for it.
When to use it
- You want to win the Buy Box specifically (not just be cheapest)
- You want to price higher than Beat Lowest when possible
- The Buy Box winner is priced higher than the lowest offer
When NOT to use it
- The Buy Box is always held by the lowest-price seller (then Beat Lowest is the same)
- You want to maximize profit above all else (use Profit Maximizer)
How it works
- Checks who currently holds the Buy Box and their price
- Subtracts your undercut amount from the Buy Box price
- Applies floor/ceiling/safety checks
- Sends to Amazon
Key difference from Beat Lowest: If the Buy Box is at $35.00 but the lowest offer is $28.00, Beat Lowest would price you at $27.99. Beat Buy Box prices you at $34.99 — $7 more profit per sale.
Example
- Buy Box price: $35.00 (held by an FBA seller)
- Lowest overall price: $28.00 (an FBM seller with slow shipping)
- Your undercut: $0.01
Beat Lowest → $27.99
Beat Buy Box → $34.99 (much better!)
The Buy Box algorithm considers more than just price — fulfillment speed, seller rating, and more. So the cheapest seller doesn't always win it.
