If you use the code GIMAG on [url]www.theeca.com[/url] (found in an article of the new Crackdown GI issue), you can receive a free, full 1 year membership (I think it's only for new accounts). You do need a credit card to sign up, but if you cancel before the 1 year is up, you won't be charged. This is a great deal for the free amazon discount. Be sure to use the coupon soon, because the article doesn't mention the expiration for the coupon.

Speaking of which, what's the CAG?

ECA Membership Benefits

The ECA is dedicated to providing a wealth of community and affinity benefits to our members. With membership, you can connect with like-minded gaming fans, explore career and educational opportunities in the business, and more. Membership can also provide a wealth of discounts, trial offers and members-only access, much of which rationalizes the cost of member dues many times over.

If you are a gamer and spend money on enthusiast magazines, or rent games and do so regularly, these benefits make it so that you would pay far less. New offers are posted frequently in the Benefits Section, and accessible once logged-in, so check back often. A partial list of discounts from our proud partners include:
