I noticed in the past 2 days that "Shopping" looks different.
Those changes may be old:

- "Sponsored link" in yellow background on top
- it now shows a sort option as "Base price"
- some time it shows the price, and under the price it shows cost of shipping and tax. I couldn't replicate it every time, I guess that it is still being worked on (Ill capture a gif when I see it next)
- added a tick box for free shipping..

I think some of these features are related to this post:
