Shop opening
Thurso and Wick are both reasonably significant towns, with a full range of shops from Woolworths to Somerfield. Opening hours are not as long as they are in big cities, but you should still not find any difficulty getting groceries or other essentials. Outside of these towns you might be limited to small village stores with short opening hours.
