The office FTC sues Amazon. 22 states in the USA help. They accuse Amazon of price control.
Amazon sells ad spots on its web site. Companies bid money for these spots. The highest bidder gets the spot.
There is a rule for the price. The winner pays a little more than the second bidder. Amazon changes this rule in secret.
Amazon uses a hidden fee. The company uses fake bidders. Real companies pay much more money.
The office says: Amazon tricks customers. The damage is many billions of dollars. Companies pass the costs to customers.
Amazon denies the claims. The company calls the lawsuit wrong. It says: The office does not understand the system.
Amazon has trouble before. One year ago, the company pays a fine. The topic is the sub system Prime.
