What is promotion / source code?
From time to time we offer special promotions or incentives to our valued customers. These promotions may be communicated via email or through special mailings like catalogs and may include a promotion or source code that is required to receive the special incentive. These special offers are not usually advertised and are only offered through the use of promotion or source codes. To sign up for such special offers, update your communication preference page when you register. You can select your preference for how, when and what you want to hear from us.
