Amazon isn't wasting any time now that its Whole Foods acquisition has gone through. Sure enough, visitors to Whole Foods stores have noticed that the grocery stores are already pitching discounted Echo speakers ($100 for the regular model, and $45 for the Dot) at very prominent stands. They're "farm fresh," according to the displays -- as if you'd find them growing in a field next to the carrots. It's a pretty shameless plug, although one you could have seen coming. Amazon craves retail space, and Whole Foods' abundance of stores (470 across North America and the UK) gives it plenty of opportunities to hawk its hardware.
