Chrome Will Now Show You Your Open Shopping Carts From Other Tabs
https://blog.googleChrome is introducing a new feature that works locally on your device to let you see your open carts when you open a new tab. So when you step away or browse on other sites, you can pick up your shopping right where you left off.
I wonder if Google can pick up on the shopping cart automatically or will there be some sort of structured data that webmasters will need to add onto the cart pages.
