I wish there was one store that sold every product I adore, but that just does not seem to be the case. However, I find Mississippi Market on West 7th Street to be a great combination of super friendly staff/customers, not too crowded parking lot and aisles, large selection of organic produce (much of which is not wrapped in plastic which I prefer), a nice salad bar/deli area that they will custom make some items for you (such as sandwhiches and burritos both with vegan options).
They do not carry every brand and item I would like them too, but they are open to suggestions on what products to offer. I wrote them asking them to carry the Tofurky vegan pizza and within a month or so they began to carry it.
To me the biggest reason I love this place is the staff. They are all super helpful in helping you verify ingredients, find an item, and are open to special orders. One day they were out of fresh vegan muffins. I was really craving one and was talking to the bakery employee about this. She offered to make up a batch on the spot! I ordered 6 to have some to take home to freeze. In 45 minutes I had fresh, hot vegan banana chocolate chip muffins. Other times, I check the bakery menu and call the day ahead and order a batch to be set aside for me. They are very easy to work with and want to please their customers. They also have a nice sitting area that is very relaxing, along with a classroom where they offer a variety of educational opportunities.
I should note, I live in Apple Valley and prefer to drive up to this coop versus going to others that are closer to my house. That is how friendly they are and are such a nice relaxing place to shop.
