I've already started recommending Garden Grocer to everyone.
I have used this service twice now and I find it very easy to use and reliable. The groceries were at our Disney resort waiting for us. I learned about this service in the Unofficial Guide to Disney World by Len Testa. It is fabulous. I would highly recommend this service.
Garden grocer was easy to use and very accommodating. I was able to change my delivery date easily. I like that they will deliver to the resort without us being in the room.
