I've been using Chef's Plate too for a little over a year now. My wife and I used to go to the grocery store weekly, buy too much or not enough and often end up with a bunch of junk food.
We've saved a ton of money and time and pretty much never go to the grocery store anymore; all our household stuff and snacks come from Amazon.
And as someone who barely knew how to cook before, I've definitely learned a lot about basic cooking since I started. (Water needs to boil before putting the pasta in
)
