I recommend Garden Grocer from my experiences using them at Disney World. Prices were reasonable and items ordered were delivered and waiting when we arrived there. The produce was fresh and as described on line.
This is a wonderful service and many of the gift shops do not carry alot of the grocery options your store provides. It was definately a convenience that I would recommend to all visiting Disney. I just wish I would have known in advance if our Hotel room was going to have a mini frig...I would have ordered more cold items. Your delivery service was well worth it!!
We used this resource for the first time on our last trip to WDW. Is was seemless and stocked our Disney resort villa for the week. Absolutely effortless and worth every penny.
