CMA warns online sellers about price-fixing
The CMA has today launched a new campaign to ensure online sellers know how to avoid breaking UK competition law.

In the build up to 鈥楤lack Friday鈥�, one of the busiest times of the year for online sales, the Competition and Markets Authority (CMA) is using this opportunity to remind sellers that discussing and agreeing price levels with competitors is illegal, and can result in serious penalties.
It goes hand in hand with the CMA writing to a number of online companies which may be denying customers the best available deals and reminding them of their obligations under competition law. The CMA has also engaged with online marketplace providers which are helping make the CMA鈥檚 advice available to online sellers.
This follows the CMA鈥檚 recent decision, in one particular case following an 8-month investigation, which imposed a fine of over 拢160,000 on an online seller of posters and frames, Trod Ltd, for agreeing with a competitor, GB eye Ltd (trading as 鈥楪B Posters鈥�), not to undercut each other鈥檚 prices when selling on Amazon鈥檚 UK website. GB eye escaped a fine by reporting the cartel under the CMA鈥檚 leniency programme.
The CMA has produced information that includes an at-a-glance summary for online sellers that explains what constitutes 鈥榩rice-fixing鈥� and what they can do to avoid it. There is also a case study that provides more detail on how the 2 sellers in the CMA鈥檚 recent investigation ended up breaking competition law.
In the Trod/GB eye case, both companies used automated re-pricing software to implement their agreement not to undercut each other鈥檚 prices. In addition, the CMA is warning software providers that they too risk falling foul of competition law if they help their clients use software to facilitate illegal price-fixing agreements, although that was not a feature of the Trod/GB eye case.
The campaign鈥檚 key warnings are that online sellers should not:
- agree with their competitors what prices they will charge, or that they won鈥檛 undercut each other on price
- discuss their pricing intentions or strategies with competitors
Stephen Blake, Senior Director of the CMA鈥檚 Cartels and Criminal Group, said:
Online markets are a hugely valuable tool for consumers to shop around and find the best value products, making the most of effective competition. But these benefits for shoppers are put at risk if the suppliers seek to restrict competition between them.
The CMA is strongly committed to tackling anti-competitive behaviour in online markets. Entering into agreements that limit price competition cheats consumers, is illegal and can have serious consequences for the companies and individuals involved.
We recognise that the majority of online sellers want to comply with the law. As we enter the peak shopping months of November and December, sellers should make sure they have read our advice so they don鈥檛 get caught out. The consequences for those who don鈥檛 can be serious.
