The companies to be investigated are: Amazon Services Europe, Amazon Europe Core, Amazon EU, Amazon Italia Services and Amazon Italia Logistica.

The competition watchdog claimed Amazon offered certain benefits to third-party sellers only if they signed up to logistical services offered by the US online retail giant.

“Such conduct may not be the result of merit-based competition, but rather of Amazon’s ability to discriminate on the basis of whether or not sellers adhere to the [fulfillment by Amazon] logistics service,” the press release indicated.

The press release added that the probe will be concluded by April 15, 2020.

“We are fully cooperating with the Authority,” Amazon said in a statement.
