Hello Sierra Beachfront.
Is there a supermarket nearby?
There is one on the road North but it would be too far too walk. There may have been a food shop a walk away where all the shops are but can't really remember.
I didn't have a car and relied on walking to a restaurant. I walked away from the town to eat in the restaurant on the headland and saw no supermarket that way. So the earlier answer is your best bet.
