on the edge of town - I think it's a Stop & Shop (used to be A&P). It's in walkable distance, but not a short walk. The supermarket in Vineyard Haven is far more convenient but quite a bit smaller.
There used to be a gas station which sold coffee for 50 cents in VH. And I found this past August a soda machine which dispensed cold 12 oz Coca Colas for
50 cents in VH. I hadn't seen that since the mid-1970s!
