Sometimes we go to a nearby farmers market. It isn't always cheaper than on the supermarket and the quality is varying. But it's fun strolling around. We look at the seasonal products and chit chat with with the farmers. A good opportunity to practice some Greek.
It's easy to grab the iPhone camera and frankly not half as intimidating in public places as my Canon EOS 450D. But I really miss the better quality pictures and seriously consider bringing it with me more frequently.
