Totally YES, I love second hand stores. So far London was the best town for me when it comes to vintage clothes, but over here there are also some good ones already since this became a huge trend in the past years. I remember what they were like when I started buying second hand clothes...I had to search veeeery long, it was like a competition: Me against the moths. But it was cheap. These days the clothes are in better condition, but they are more expensive of course.
I love second-hands! I´ve been "hunting" over 4 years or more and I almost did´t go to normal shops anymore. Over half of my closet is from second-hand. I really like the feeling that I wear something with history. For example - I bought leather jacket made in Italy for $5 and the previous owner was some Italian boy named Ricardo (the jacket was in little boys section and was signed, so cute)
