It is reported that a large number of advertisers were affected, with the lawsuit stating they paid more than intended due to a price increase.

The retailer has responded to the lawsuit, expressing disagreement with the claims. A statement was provided, though its full content is not specified here. Further information on the lawsuit and the retailer's response can be found through the original source.
