Yes, California will dry clean your shirt for $2. But you might not be happy with what you get back.
Not only do the shirts never look (or smell) right, twice, they wound up burning a little hole in the clothing.
It's not worth the savings if they destroy your outfit, and both times they insisted that it must have already been there (even though it was on the front of a white shirt one of the times... how could I miss that?)
So as tempting as the cheap price may sound, it's not worth it. Stay away.
