They have a $40 minimum order for food/drink items. On that, it is a $12 delivery charge. I believe it's $12 for anything up to $200, at which point delivery is free.
We ordered from Garden Grocer in August and were very happy with the service. I think we purchased about $50-$60 worth of items, had the $12 delivery charge, and also pre-tipped $10. Everything was exactly as promised.
We ordered milk, cereal, muffins, yogurt, soda pop, chips, crackers, and cheese. We will use Garden Grocer in the future. They have earned my business.
