I know for me, not very often at all. Maybe 10% of the time. Maybe my expectations are too high? Descriptions are usually inaccurate, and/or pics are airbrushed, or just taken in a way to hide flaws. I get to wherever I am going, and am usually disappointed. Why do I keep going back with such a low success rate? I really ask myself that often. Perhaps I just think I'll strike gold some day? I guess it's like playing the lottery!
