Garden Grocer was great. Efficient, worked well with my resort, communicated with me several occasions before my trip and met all my expectations. I'd recommend them and I'd use them again on my next vacation.
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.
Garden Grocers made our trip to Orlando considerably less expensive and more healthy than it would have been otherwise. We had yogurt, milk, fruit, and juice available for our kids upon arrival. I highly recommend this service.
