Good question, Billy. Single page apps now play a huge role in modern web development and SEO issues make sense.
Before October 2015 Google suggested to use the following scheme:
http://example.com/page?query#!state
I.e. in your examples it will be yoursite.com#!products and yoursite.com#!prices. So main role in the understanding correct page URL played the ! symbol.
Here is the full recommendations (It's outdated now, read below):

In October 2015 Google launched new scheme and deprecated the old one.
So here is the new announcement:
https://webmasters.googleblog.com/2015/10/deprecating-our-ajax-crawling-scheme.html
The major news of this announcement is that now Google DOES index dynamic pages.
But you need:
- Make sure your JavaScript files can be indexed by Google (because Google run it in their crawler like just modern browsers)
- Make sure you use HTML5 mode in URL scheme (AngularJS supports it). Read more here:
