It’s the beginning of a new week for most of us, but the beginning of a new era for Whole Foods and Amazon. The grocery store’s acquisition by the Everything Store closes this week, and the companies have already kicked off their in-store relationship with Echo speakers in the produce section and lower prices on selected items around the store.

If customers missed the news that Whole Foods would become part of Amazon today, they certainly knew once they saw a prominent display in the produce department.
