This service is great and a MUST if you're staying at a Disney resort/property. The money we saved on bottled water, alone, as opposed to buying in the parks, was worth it.
I used Garden Grocer for a few necessities for my trip. I found their prices to be reasonable and their customer service excellent. I would use them for every trip to florida!
The service was excellent. The individuals I dealt with we're courteous, helpful and a pleasure to deal with.
