I don't like to give pricing advice. Since I cannot see your junk, I don't feel comfortable telling you how much you should charge.
I recommend going to several yardsales in your area before you hold your own yardsale to get a general idea of the going rate of things.
Also, there is no need to write to tell me that I spelled yardsailing wrong. I did not.
So basically that leaves the only logical, main reason to email me - to send glowing fan mail. (Media requests also ok).
