Yes, they have a delivery service that will bring what you want to on-site and offsite hotels. Their web addressis gardengrocer.com
There is a $40 minimum and a $10 delivery fee, but it was worth it to us not to have to worry about it. Anything perishable that arrives before you do is marked as such and is kept refridgerated. Garden Grocer has gotten rave reviews (for the most part) on the DIS.
