Garden Grocer is the place to order your online groceries when going to Disney. The website is easy to use, the order process was intuitive and the post-ordering customer service was excellent. We received all of our groceries on time, intact and to our quality expectations. Not only would I recommend them for ordering groceries online, I would go as far as to say they are the only online grocery store that I will use when returning to Disney.
I would highly recommend Garden Grocer, it's easy to use and they were very prompt with their service.
It is good to know my groceries will be at the hotel when I arrive. Saves a lot of vacation time.
