That generally means that you're paying for a digital (downloadable) CD instead of a physical item.

But if it's not a physical product, it's not a CD. Plus, it indicates a delivery time of one week. And someone else I know encountered one that was backordered, which would not be the case with something that's digital only.

In that case, it has downloadable content that's included with it as well. Bonus tracks or movies.
