Answer:
To buy a digital camera, first decide what you are looking for. A point-and-shoot camera is cheaper and appropriate for most people, with many automatic settings, while a digital SLR camera is best for those who are experienced in photography or who want more options and the ability to switch lenses. Other factors to consider are the number of megapixels, battery life, etc. Read consumer reviews of different brands and models, then compare prices from several different stores, and choose what's best for you.
