we have used twice for our Disney vacations and both times it has worked great.
Garden Grocery is a must when coming to Disney even if you are on the meal plans. From ordering bottled waters to keep you hydrated throughout the day. To snacks that hold the family over until the next meal or when you are on a long ride line. They are incredibly quick and provide regular updates so you know where your items are going to arrive. Truly the best!!!
Excellent service, it was great to have our groceries waiting for us on our arrival at our hotel. I would definitely recommend Garden Grocer.
