We have used garden grocer for years. It is perfect to add food/drinks to your room for packing things for pool or parks. Saves a lot of time, effort, and although deliver charge seems like it adds a little it saves you in the end.
Everything exactly as advertised.
This was our first time using this service and it was a great experience. The ordering process was easy - especially the ability to add on items that we missed the first time. The order was delivered during the specified window and held at the resort front desk so that we could bring it to our room at our convenience. This was so much easier than thying to pack things ourselves or take the time out of our vacation for an offsite grocery trip. We will definitely be using Garden Grocer on all future Disney trips.
