If you shopped on Amazon in the UK, you may have overpaid.
Discover how Amazon's pricing policies prevent sellers from offering lower prices elsewhere on the internet and lead to higher prices on Amazon.
The Association of Consumer Support Organisations (ACSO) is bringing a class action against Amazon to help compensate consumers who have overpaid on Amazon.
Amazon's pricing policies at a glance
Amazon requires third-party sellers to comply with certain pricing policies. These policies may have limited competition and increased prices on Amazon.
What you need to know about Amazon's pricing policies
Amazon is trusted by millions of consumers for its lowest available prices.
But Amazon is only able to offer the lowest price because of anti-competitive price restrictions that prevent third party sellers from selling their products at lower prices on other platforms - all to keep you shopping on Amazon.
How Amazon's pricing policies lead to higher prices on Amazon
By preventing sellers from offering lower prices elsewhere online, Amazon protects itself from price competition because consumers can't find a better deal elsewhere.
Since Amazon is not worried about being undercut, it charges sellers higher fees, which consumers pay for in the form of higher prices.
Every purchase, no matter how big or small, adds up. Over time, UK consumers may have collectively spent millions more than they should have. If you have ever bought something on Amazon from a third-party seller, you may have been affected.
What we're doing about it
To help compensate consumers who may have overpaid because of Amazon's pricing policies, the Association of Consumer Support Organisations is bringing a legal action against Amazon on behalf of UK consumers.
The Association will seek compensation for over 45 million UK consumers who may have overpaid on Amazon. If the legal action is successful, a person who bought a product from a third-party seller on Amazon’s UK retail marketplace will be entitled to compensation.

How Amazon's price parity policies drive up prices on Amazon
In a competitive market, Amazon would have to offer sellers low fees to compete with other platforms, which would result in lower prices for you.
Otherwise, sellers would offer higher prices on Amazon to reflect the higher costs of selling on Amazon.
Higher prices on Amazon would drive customers away from Amazon and towards other e-commerce platforms.
Since at least 2019, Amazon has required sellers to agree not to offer lower prices for the same product elsewhere on the internet. This obligation is a part of sellers' standard contracts with Amazon.
Because of Amazon's pricing policies, consumers cannot find a better deal elsewhere online.
Since Amazon does not have to worry about being undercut, Amazon charges sellers higher fees, which you end up paying for in the form of higher prices on Amazon and other online retailers.
