Been using Mama Earth Organics for a year now and we do most of our groceries with them (i.e. Vegetables, selection of fruits, milk, eggs, yoghurt and occasional speciality items).
Great customer service, super responsive and eager to resolve issues
Only downside to the service is the basket gets boring over time. Like having beets, fiddle or squash for 4-6 weeks in a row. You can add $2 to customize your basket choice but usually within the price range the alternatives are limited. Sometimes the compromise for vegetable is 1 avocado or 2-3 fruits When replacing items like Bok Choy, most of the time I am only allowed 0.5 lbs
Would be nice if they can do meats as well so it can become my full organic / delivery grocer
