What “legacy” means: throughout Seller Snap you’ll now see your current repricer labeled the legacy repricer (or “legacy models”). “Legacy” simply means the version you’ve been using until now. It is still fully available, and you can switch between it and the new engine whenever you like. |

1. What’s new
Our repricer just got a major upgrade. The new engine is an evolution of the Seller Snap repricer you already know. Built on a decade of real-world Amazon data, more powerful engineering, and AI, it makes better decisions across more situations: stronger on competition, smarter when prices drop, and at scale, more profitable. It’s focused on one thing: helping you make more money, not just win the Buy Box.
What makes it different
It sees the Buy Box shoppers actually see. Amazon’s Buy Box winner can change from one region to another, so the same price can win in one area and lose in another. The new engine prices to the real, per-region answer, weighted by where your shoppers are.
You set the strategy; the engine does the math. Choose how aggressive you want it to be and the engine handles competitor counts, profit estimates, fee thresholds, and geographic weighting automatically.
Your price limits are always respected. Your minimum and maximum prices are always enforced, along with Amazon limits like the Competitive Price Threshold (CPT) and any Minimum Advertised Price (MAP).
2. Aggressiveness
The new engine runs on a single aggressiveness scale. You decide how hard it competes for the Buy Box, from less aggressive to more aggressive. There are three settings.
Conservative
Protects your margin first. It will step aside from the Buy Box rather than price too low. This is even more conservative than your legacy default AI. Best for: high-margin products, slow movers, or when you’d rather hold stock than sell at a low price.
Balanced
A healthy balance between winning the Buy Box and protecting profit. This is the closest setting to your legacy default AI, and a solid everyday default. Best for: most products.
Aggressive
Pushes harder for Buy Box share and accepts lower margins to get there. This is the closest setting to the legacy Win Buy Box strategy. Best for: competitive categories or when growing volume and market share matters.
Quick reference: Comparability
Aggressiveness level | Closest legacy strategy |
Conservative | More conservative than the legacy default AI (no direct equivalent) |
Balanced | Legacy default AI |
Aggressive | Win Buy Box |
Surge is a separate power mode, not a setting on the scale above. It’s a high-intensity tool built for liquidation and clearance, when your goal is to win the Buy Box at almost any cost. Because it trades away margin, it isn’t meant for everyday use. |
3. How to turn on the new engine
There are two ways to switch a product to the new engine. We recommend using a Repricing Preset so you can apply it across many listings at once.
Option 1: In a Repricing Preset (recommended)
Go to Tools > Presets > Add a preset.
Name the preset and choose which stores it applies to (a single preset can now cover multiple stores, for example, US, Canada, and Mexico).
Set the primary method to AI, then under Aggressiveness choose Conservative, Balanced, or Aggressive.
Apply the preset to the SKUs you want on the new engine. Tip: start most products on Balanced.
Option 2: On a single listing
Open the listing and click View details to pop out the listing panel.
Go to the Repricing tab.
Choose AI (rather than Rule-based).
Under the new engine, select Conservative, Balanced, or Aggressive.
The legacy models (legacy default AI and Win Buy Box) are still available here but are marked “leaving soon.”
4. Applying it at scale
Can I apply the new engine with bulk edit? Yes. Once you have a preset created (option 1) you can apply it to many SKUs at once, using bulk edit under the field “Repricing preset”.
5. Frequently asked questions (FAQs)
How is the new engine different from the legacy algorithm?
It’s an evolution of what you’ve used for years: the same foundation, made stronger. With more data and better engineering, it makes faster, better pricing decisions across more situations.
Why should I switch?
The new engine uses more precise data to make better pricing decisions, and in our testing, it has left sellers more profitable at scale. There’s no pressure to switch right away. Try it on a few products and compare the results for yourself.
What is actually different about how it works?
The legacy algorithm reacted to price changes as they happened. The new engine has access to data that points to the winning price before it acts, rather than testing prices one step at a time. It also reads competition at a more granular, per-region level, so it makes a better decision on each listing.
How fast does it react to a Buy Box change?
Roughly 30 to 60 seconds for listings Amazon flags as having just lost the Buy Box. Your highest-value listings are refreshed most often.
Which setting is closest to Win Buy Box?
Aggressive is the most aggressive point on the scale, and the closest to the legacy Win Buy Box strategy. If you need to chase the Buy Box even harder for a clearance push, use Surge (a separate power mode).
Which setting is closest to my old default AI?
Balanced.
Is there anything more conservative than my old AI (legacy)?
Yes. The Conservative setting is more margin-protective than the legacy default AI.
Can I still use my custom conditions and rule-based repricing?
Yes, fully. Custom conditions are unchanged and fully supported. The new aggressiveness settings are an addition, not a replacement. You can still add alternative methods to a listing or preset.
Will the new engine respect my minimum and maximum prices?
Always. It will never price outside your configured range, and it also respects Amazon’s Competitive Price Threshold and any Minimum Advertised Price.
Does the new engine respect the Reduced Profit Range (fee “gray zones”)?
Yes. It automatically detects price bands where a higher price would actually leave you with less profit (because of a fee jump) and steers to the more profitable side of the threshold. No setup needed.
How does it handle a suppressed Buy Box?
When Amazon isn’t showing a Buy Box, the engine relies on the available market data and your setting to position your price, and resumes normal competition as soon as the Buy Box returns.
What happens when my stock is backordered?
The engine raises your price so you don’t win the Buy Box on something you can’t ship, and it never lowers your price while a listing is backordered. Normal repricing resumes once stock is back.
What happened to the legacy algorithm? Is it being removed?
The legacy algorithm is still available for now, and switching is your choice: move a product to the new engine when you’re ready, and switch back at any time. Over time the legacy version will be phased out as the new engine becomes the standard, but there’s nothing you need to do today, and we’ll guide you through any change well in advance.
Is this going to break my current setup?
No. You opt in one product at a time, at your own pace. Your existing conditions, strategy settings, and repricing rules stay exactly as they are. The new engine works underneath the same workflow you already know.
