Amazon A/B Price Testing: Boost Profits with Smart Repricing Strategies

In the hyper-competitive world of Amazon selling, every cent counts. What if you could experiment with different price points just like marketers test email subject lines to see what drives the best results? That’s exactly what Amazon A/B price testing can do.

This guide will show you how to run pricing experiments using a repricing tool like InstaRepricer to find your optimal selling price without sacrificing your Buy Box win rate.

What is Amazon A/B Price Testing

A/B price testing is the process of offering two different price points for a product at different times, and analyzing the performance of each version. The goal is to discover which price drives:

Higher sales volume
Better margins
More Buy Box share
Improved conversion rate

You’re not just guessing anymore you’re making data-backed pricing decisions.

Why Amazon A/B Price Testing Matters

Many Amazon sellers either:

Set a static price and hope for the best
Use aggressive repricing that undercuts competition (and their profits)

A/B testing offers a better way: Strategic pricing based on actual buyer behavior.

Benefits of Amazon A/B Price Testing:

Increase profits without losing sales
Find your product’s “price ceiling”
Reduce race-to-the-bottom repricing
Improve Buy Box strategy over time

How to do Amazon A/B Price Testing

You can’t technically split traffic like in email marketing, but you can alternate prices over a period and compare outcomes. Here’s a simple workflow:

Step 1: Choose a Product to Test

Pick a product with:

Consistent sales
Buy Box eligibility
No major seasonal spikes during the test window

Step 2: Define Test Prices

Decide on two price points:

Price A: Your current average or slightly below
Price B: A higher price (5–10% more)

Example:

Price A: $24.99
Price B: $26.99

Step 3: Set Up the Experiment in InstaRepricer

With InstaRepricer, create two repricing rules:

Rule A: Operates on certain days or times
Rule B: Alternates with Rule A (e.g., different days/times)

Use time-based or day-parting rules to rotate prices automatically.

Step 4: Run the Test (Minimum 2 Weeks)

Run the test long enough to:

Gather statistically significant data
Account for weekday/weekend variation

Step 5: Analyze Key Metrics

Look at:

Units sold
Conversion rate
Total revenue
Buy Box percentage
Profit margin

Whichever price wins on your core metric becomes your new benchmark.

Example of a Real-World A/B Test

Price	Units Sold	Revenue	Buy Box Share	Profit Margin
$24.99	100	$2,499	78%	21%
$26.99	90	$2,429	68%	26%

Although the higher price sold fewer units, it delivered better margins making it the smarter choice for long-term profitability.
