Tomatoes require a little work, but there are plenty benefits of growing your own. Since they're usually trucked in from far away, store-bought tomatoes often have a huge carbon footprint. On top of that, they're expensive, heavily sprayed with pesticides and flavorless when out of season. Homegrown tomatoes, on the other hand, are high-yield, juicy, rich and you know exactly what chemicals (if any) have gone into them.
There's also no rush to harvest them -- ripe tomatoes will keep for about two weeks on the vine. At the end of the season, and before the first frost, wrap green tomatoes in newspaper and store them in a cool, dry place where they'll ripen slowly to last through autumn and early winter.
