Do not buy bundle themes for WordPress if you’re not going to use them immediately. WorPpress gets updated and all of a sudden nothing works like it is supposed to and usually developer’s theme support is no good.
You’ll be better off buying one theme and using it immediately. But before that check the theme’s reviews and the support section to learn more about the functionality of the theme.
Update: Still working on my new website. I’m trying to make work a one page flat theme so I can use it as a landing page. But nothing is straight forward as usual with designing websites.
If you are sending newsletters or using feedburner don’t forget to ask your subscribers to add your mail to their contact list or address book so your mail won’t end up in their Spam folder.
