Without seeing the specific code used by Google for the snippet, this appears to be rich snippet markup for Products, as covered here: Google Webmaster Tools - Rich snippets - Products.
Product Offers includes the following properties (among others):
- price
- currency
- quantity (which the top snippet appears to have)
Note that this text appears in light grey, as visible in this video at 0:17 (when price is highlighted).
Other properties includes offerURL
- a URL to the product's webpage, which the second snippet may have used. Alternatively, it could have used the url
property as described here at schema.org/Product
Note that currently the page for Data Highlighter for Products is not available, however, it should use the same schema.org/Product schema, as similarly indicated under "Event Tags" in Data Highlighter - Events
