What is competitor filtering?
Competitor filtering lets you control which competing offers RepriceLab considers when calculating your optimal price. By default, RepriceLab evaluates all visible offers on a product listing. Filtering allows you to exclude competitors that are not relevant to your strategy — for example, low-quality FBM sellers you do not realistically compete with for the Buy Box.
Filters are configured per repricing rule (preset) and apply to all products assigned to that rule.
Filtering FBM sellers
FBA and FBM offers are treated differently by Amazon's Buy Box algorithm. Because FBA offers come with Prime shipping, Amazon typically prefers them over FBM offers at the same price.
If you are an FBA seller, you can configure your rule to:
- Ignore FBM sellers entirely — RepriceLab only competes against other FBA offers
- Allow a higher price than FBM — Set an FBM adjustment so RepriceLab can price $X or X% above FBM sellers while still considering them in the calculation
This prevents RepriceLab from unnecessarily dropping your price to beat a low-quality FBM offer that would not win the Buy Box anyway.
Filtering by seller feedback rating
Sellers with very low feedback scores are less likely to win the Buy Box, even if their price is lower. You can tell RepriceLab to ignore sellers below a minimum feedback threshold:
- Minimum feedback count: Ignore sellers with fewer than N total feedback ratings (e.g., exclude sellers with fewer than 10 reviews)
- Minimum feedback rating: Ignore sellers below a percentage rating (e.g., exclude sellers below 90% positive feedback)
These filters help you avoid competing against low-credibility sellers whose prices drag down your margins without posing a real Buy Box threat.
Filtering by dispatch time
Sellers with long dispatch times (e.g., 10+ days) are heavily penalized by Amazon in Buy Box eligibility. You can exclude them from your competitor set by setting a maximum dispatch days filter. For example, setting max dispatch days to 3 means RepriceLab ignores any offer that takes more than 3 days to dispatch.
Country-based filtering
On some marketplaces, offers from sellers based in certain countries may have higher shipping times or lower buyer trust. RepriceLab allows you to filter competitors by the seller's registered country of origin. Use the Include Countries setting to restrict your competitor set to sellers from specific countries.
Excluding specific sellers
You can exclude individual sellers by their Seller ID. This is useful for excluding known resellers, your own duplicate accounts, or brand-authorized sellers you do not wish to compete against. Enter the Seller IDs (comma-separated) in the Exclude Seller IDs field of your rule.
Ignoring Amazon as a competitor
When Amazon itself is selling on a listing (as a first-party seller), it is very difficult to compete on price for the Buy Box. Many sellers choose to exclude Amazon from the competitor set and instead set their No Competition Action to raise price to the maximum when no qualifying competitors remain.
Enable Exclude Featured Merchant in your rule to ignore Amazon's own offer when calculating your target price.
No competition action
When all competitors are filtered out (no qualifying offers remain), RepriceLab does not leave your price unchanged — it applies your No Competition Action:
- Increase to maximum: RepriceLab raises your price to the maximum price you have set (recommended for Maximize Profit)
- Hold current price: Your price stays as-is until a qualifying competitor appears
- Set to minimum: Price drops to minimum (useful for Boost Sales scenarios with no competition)
