I've always had great experience with Garden Grocer. The website and the App are so easy to navigate and order from. And their selection is above what most provide. I highly recommend them. And yes it was cheaper and easier than ordering from Amazon and having it delivered to the resort. It also works seamlessly with the resorts. *I've only used at Disney World Resorts*
It was nice after a long trip to have everything we ordered already at our room when we showed up at night!
We stayed at a Disney resort during our vacation to Orlando, and with their help with transportation, there was no need for a rental car - which also prevented us from making a trip to the grocery store. We had no intention of eating at a restaurant for every single meal, so Garden Grocer saved us money by delivering groceries for the week right to our resort. Convenient and money-efficient!
