About this offer

The bonus is calculated on the base trade-in value of qualifying games and accessories and is added as store credit rather than cash. Pro members receive an additional percentage on top of this bonus.

Trade values change weekly and are highest in the weeks before a major release. Discs must be free of deep scratches and cases and manuals should be present, as incomplete items are valued lower or refused.

What the offer applies to

  • Qualifying games, controllers and accessories

What is excluded

  • Cash trade-in option
  • Consoles in some promotional periods
