I actually would look into Amazon's Prime Now (love it) or Instacart (uses Publix) The delivery is cheaper on both of them.
Nothing against Garden Grocer really but you can pick what you want the day of and there are lot of options from the Instacart as well as Prime Now. Prime Now's problem is lack of produce IMO
We used Garden Grocer when we went in April. After I completed my order, we thought of a few more items that we wished we had ordered. (we actually did this twice) Both times, I was able to go in and add those items to our order without any extra charges. The groceries all arrived promptly and in great shape (like the fruit). We will definitely use them again.
