Both times I have used Garden Grocer the groceries arrived before I did! It's great getting to your room after traveling and having food and water waiting for you.
We used Garden Grocer for ten dirt time this past week while we were in Disney. The groceries were delivered to our cabin in the campground before we even checked in! It was awesome. The groceries were put away and everything on our rather large order was correct and fresh.
Saved me from renting a car to run the to grocer. Loved the service!
