This was my first time using the Green Grocer but certainly won't be my last. It was easy, accurate and reasonably priced for the service provided.
If you're wanting to save some cash while in WDW by cooking your own food, this is the way to go. Easy to set up and easy to get delivered to your room - all you have to do is show up and cook.
I found out about this service from my sister. It took all of the hassle out of getting food items during our vacation. Having my items waiting at bell services when I arrived allowed me to make better use of our time. Highly recommended this service.
