"Race to the bottom" is every Amazon seller's nightmare: everyone undercuts each other until no one makes a profit anymore. In this article, we show you how to win the Buy Box with intelligent repricing without destroying your margins.

The Problem with Aggressive Repricing

Many sellers set their repricer to "always 1 cent cheaper" hoping for more sales. This works short-term, but long-term the following happens:

Typical scenario: A product starts at 29,99€. After 2 weeks of aggressive repricing, it sits at 19,99€. The margin? Practically zero.

Intelligent Repricing Strategies

Strategy 1: Minimum Price with Margin

The most important step: define a minimum price that guarantees your desired margin. Your repricer should never go below this price.

// Minimum Price Calculation
Minimum price = Purchase price + FBA fees + Amazon fee (15%) + Desired margin

// Example:
Purchase price: 10€ + FBA: 3€ + Fee: 3€ + Margin: 4€ = 20€ Minimum price

Strategy 2: Selective Competition

Not all competitors are real rivals. A smart repricer lets you ignore certain sellers:

Pro tip: Focus only on the top 3 competitors with FBA and a good rating. The rest is irrelevant for the Buy Box.

Strategy 3: Price Corridors

Instead of "always cheaper", use price corridors:

// Price Corridor Rule
IF Competitor price > 25€
  THEN My price = Competitor - 0,50€

IF Competitor price between 20-25€
  THEN My price = Competitor - 0,10€

IF Competitor price < 20€
  THEN My price = Minimum price (don't undercut!)

Strategy 4: Time-Based Repricing

Demand fluctuates throughout the day. Take advantage of this:

Practical Rule Templates

Template 1: Conservative (margin-focused)

// Conservative Repricing
Minimum price: Purchase price + 30% margin
Maximum price: Minimum price + 40%
Undercut by: 0,01€
Ignore: FBM-Seller, Rating < 95%, Out-of-Stock

Template 2: Aggressive (volume-focused)

// Aggressive Repricing (only for fast movers)
Minimum price: Purchase price + 15% margin
Maximum price: Minimum price + 20%
Undercut by: 0,05€
Ignore: Only out-of-stock sellers

Template 3: Premium (brand-focused)

// Premium Repricing for branded products
Minimum price: RRP - 10%
Maximum price: RRP
Undercut: Never below minimum price
Strategy: Buy Box through better service, not price

When You Should Give Up the Buy Box

Sometimes it's better not to win the Buy Box:

Important: Better fewer sales with a good margin than many sales without profit. Your goal is profitable growth.

Conclusion

Intelligent repricing doesn't mean "always the cheapest", but rather:

  1. Define minimum prices that protect your margin
  2. Filter competitors down to the relevant ones
  3. Use price corridors instead of linear undercutting
  4. Sometimes give up on the Buy Box
