Google announced they made some improvements to Google Shopping before the holiday season – keep in mind, it is a paid product placement service now.

The new features include:

Holiday Shortlists: Premade categories of products you may want to by in the categories of electronics, toys, etc.
Custom Shortlists: You can create your own shortlists over here. This will let you keep track of products that catch your eye, compare products at a glance and collaborate with friends and family.
Better Browsing: Adding product preview details like sizes, colors and description, and find out if it’s available at a nearby local store.
360° Product Views: You can view the products from all angles with this feature.
