Being from the UK we didn't know any grocery delivery services in the USA so took advice from people on TripAdvisor who recommended Garden Grocer now I'm recommending them to you.
We used the Garden Grocer for the first time this month during our trip to Disney World. The service was wonderful and very convenient! I ordered the food in advance and received a confirmation notice the very next day (as well on the day of delivery). This service is "a must" for families flying into the resort.
A wide selection of products was available to choose from. We ordered snacks, fruits, veggies, & drinks for our stay at the Disney World Resort. Items were delivered on time to our hotel and communication was excellent via text & email. The delivery charge is excessive especially considering that the prices for each product is already higher than a regular grocery store, plus you have a minimum dollar amount that you must purchase. Overall it was a convenient service because we were not renting a car and had no other option to order groceries. It was expensive but probably much less expensive than buying the same products at the resort hotels or at the Disney World Parks.
