We have used them several times and always with excellent results.
Great service complete with an order confirmation phone call and text confirmation after delivery. Gave us convenience of groceries in our hotel room without having to take time out of our trip. Should note that delivery charge was pretty much the same as it would cost for taxi or other transportation to go to store ourselves and the product quality and selection was good. Plan to do this for every trip!
We have used the service two times on our Disney trips and could not be more pleased. We have already told others including at the pool when other guests saw us with our groceries.
