I checked out the Prime Day kitchen listings over at the Wirecutter.
Prices I see (US Prime Member) as of ~ 1PM PDT
Anova WiFi @ $69.99, Bluetooth is $74.99, Nano is not showing any Prime deal and is still priced @ $99.
Joule @ $130 Edit: Now up to $150
Vitamix 5200 @ $279.95
These prices seem to be shifting up and down over time. In some cases, you don't see the "Prime Day" prices unless you are logged in as a prime member.
All seem like good prices but nothing I need so far.
I've got $10 to spend from using the Whole Foods app and may apply it to a cookbook, along with promo code PRIMEBOOKS18 to save $5.00 when you spend $20.00 or more on Books
