Tomatoes are very cheap locally so it is not practical to preserve them. But sometimes there are seasons that the price is high because of very limited supply. And it is better to use fresh tomatoes in cooking than preserved ones like the ones sold in cans. Anyway preserving tomatoes has its advantages also because you will have a constant supply of tomatoes all year round.
