Most of the shops aren't clickables yet, and the ones who can be visited only sell items useful for Quests.

On top of the map, next to the pond, there's Hickory Hardware & Woodworks. This shop will sell tools useful for various crafts. It will probably open when the quest system starts.

Next to it there's the Cider Mill which is closed too. It looks as if it will sell the items we need to make apple cider.

The stall with the blue top is the Green Produce Stand which will probably sell things from Farmer Noggin's farm (like milk, eggs and fruit).

You can also visit the Barn (the large red building next to the Silo) and the Noggin Farmhouse next to it.
