We found out this is the way to go. We order and Garden Grocers will deliver. Our groceries were delivered directly to our villa at Disney World. This made our vacation more enjoyable, no car to rent to go to grocery store. Everything we ordered was delivered in a timely manner. Way to go Garden Grocers.
Garden grocer is so incredibly efficient - they take one less stress out of Disney park planning when traveling, especially with young ones. Our impetus to use them was to save a little money at the park, if your family wants more than one 'snack' a day your jammed into paying 2.50 for a bottled water. I chose several of the 'Store Brand' items (specifically for cases of water and paper goods) and it proves far more reasonable than others. We highly recommend garden grocer!
Don't do Disney without Garden Grocer! I love having breakfast and snacks ready in at the resort. It's a real convenience and money saver!
