I loved the bundle idea! Two suggestions:

* Not everyone is familiar with everything. Can you add a section to the site that better describes what the included services can be used for. I don't mean full-blown tutorials, although links to these would be great. Right now the descriptions are just publicity blurbs for each service.

* Can you add voting so that people nominate what services/books they want to see in the next round of such a bundle offering, if you want to continue this startup bundle idea.
