GameStop has settled a suit, requiring the company to post signs in California stores warning consumers if certain games have additional fees for online content in a secondary sale. The company will also reimburse "consumers who purchased qualifying used games" with a $10 check and a $5 coupon if they are a PowerUp Rewards members and a $5 check and a $10 coupon if they aren't.

"The in-store and online warnings are an important benefit under the settlement as well, because if GameStop discloses the truth to consumers, it is unlikely that they will be able to continue selling used copies of certain games for only $5 less than the price of a new copy," said Mark Pifko, attorney for firm Baron and Budd and counsel in the lawsuit. "In fact, we already know that not long after the lawsuit was filed, GameStop lowered prices for used copies of many of the game titles identified in the lawsuit."

The firm has set up a Facebook page for affected consumers. We've contacted GameStop for comment.
