If you have been in business for less than 3 years and you have fewer than 10 employees, you may be eligible for a free 3 year MSDN Subscription.

This means you can get all your server software, operating system and such for free. These are not trials but fully licensed, non-expiring software. This equates to a saving of over $33,000 dollars over 3 years. Software and operating systems are a must for any business but the cost can make you bankrupt before you start. This will cure that problem!
