I had no idea this Google Express app existed (It's not available in my region of the world). It's a shame they force you to use it, over just adding to a shopping list in Google Keep. I was considering getting the Home Mini but now I'm not so sure (grocery list, weather check, and general help (timer/conversions) while cooking would have been my main usage)
