You can buy just about "anything" in the local supermarkets ...
One thing you should buy is water.
- tea bags
- nappies (called fixies)
- food ...
The water from the tap is salty. You can get water in 2, 4 or 8 liter bottles.
Most supermarkets in the resorts only open during the summer, so they tend to be a bit more expensive than the supermarkets (and hypermarkets - a supermarket usually has some 1,500 articles in stock, a hypermarket some 5,000) in the towns and villages.
