If you know how to use Amazon's interface it's possible to see the list of books online so you don't have to do all the browsing on the Kindle, but you still have to 'buy' it from the Kindle.
It's sort of a hidden link or a special way of narrowing search results with the criteria on the left side of the page. If you google I'm sure you can find instructions.
Here's the super-secret password for the clubhouse.
In the search box on the main amazon.com page, there's a drop-down list on the left hand side of the text entry. Click that and change it to "Books". Now just hit search (you can leave the text field blank). That will bring up a search results screen with a bunch of filter groups on the left. Scroll down and select "Kindle Edition" under "Format". After the page reloads, scroll down even further and you'll have a checkbox for "Prime Eligible". Select that, and you'll have only the books you can rent with Prime. You can then further refine by genre, search term, whatever.
You can buy it from your phone or computer. Even if it is a Mac. You pick which device you want it sent to. And I totally don't get that y'all are saying ebooks cost more than trad.and "awful" selection? What don't they have?
