We've been using Garden Grocery for as long as I can remember. Our oldest has food allergies, and when we travel to Disney, we are careful to bring along food that he can eat. GG went out of their way to add items for allergy folks over the years, but when we first started using them, these items were special requests. And it was super easy to make special requests. High customer service. They care and they check back to make sure everything goes well. We use them every trip and recommend them.
For those that like to be organised before they travel, then this is an excellent service.
We ordered (from Canada) online to make sure that we had cereal, milk, cream and snacks for the kids while at Disney and it would have worked out great but Disney Riverside employees "lost" our groceries, when they "found" them they replaced the dairy with their own industrial brands (YUCK). GG did everything they could to help, even calling and making sure that Disney employees found our items. I will use GG again (and again, and again).
