With the latest release of the Adobe Creative Suite, there are two major ways you can get the products. The traditional method is to order the product(s) of your choice on a DVD. It requires a larger upfront cost and you can use only the applications included in the suite you purchase.
Another option is the Adobe Creative Cloud. You pay a monthly fee for access to any and all of the applications in Adobe Creative Suite 6. This can be handy if you only need to use a specific product for a short period of time or if you simply don’t want to make the upfront investment in the DVD.
Adobe is running a special offer during August 2012 where owners of existing CS products can get a subscription for $29.99/month (40% off). I certainly can’t tell you the best decision for your needs, but this special pricing makes the Adobe Creative Cloud a very attractive option.
