Free Amazon Price Comparison Tool
The same product can cost far more in one country than another. Enter one ASIN and see its BuyBox price across every major Amazon marketplace — each converted to USD so you can compare like for like.
How the Amazon price comparison tool works
Enter one Amazon ASIN and your email. The tool queries the current BuyBox price for that ASIN across all 18 major Amazon marketplaces in parallel — the US, UK, Germany, Japan, Australia and more — then converts every local price to USD using live exchange rates so you can compare them on a level playing field.
Data is fetched live from the Asgard Data API at the moment you submit. Because ASINs are region-specific, a product may not exist in every marketplace — those markets are clearly marked "Not sold here" rather than dropped, so you always see full coverage.
Why do Amazon prices differ by country?
Currency and FX movement
The same product is priced in each marketplace's local currency. As exchange rates move, the real cost in USD drifts apart even when the local sticker price never changes.
Local demand, taxes and shipping
VAT, import duties, fulfillment costs and regional demand all feed into the BuyBox price. A product with thin competition in one country often carries a premium there.
Seller mix per marketplace
Different sellers win the BuyBox in different countries. Where Amazon itself is the seller you often see sharper pricing than a marketplace served only by third parties.
Frequently asked questions
How does the Amazon price comparison tool work?
Enter one ASIN and the tool checks the live BuyBox price across all 18 major Amazon marketplaces at once, then converts each local price to USD with live exchange rates so you can see the cheapest and most expensive markets at a glance.
Is the tool free and do I need an account?
Yes, it is completely free and no account is required beyond your email address. It is powered by the Asgard Data API, which checks Amazon in real time.
Why is my product missing in some marketplaces?
ASINs are region-specific, so the same identifier does not always exist in every country. When a marketplace has no listing for the ASIN, the tool marks it 'Not sold here' instead of showing a price.
How are the USD prices calculated?
Each marketplace returns a price in its local currency. The tool fetches live USD exchange rates and converts every price to USD so the comparison and the price-spread percentage are like for like.
Can I run this across many ASINs automatically?
Yes. The same BuyBox data is available programmatically through the Asgard Data API, so you can compare prices across marketplaces for an entire catalog on a schedule.
