Question:I am doing a report for my job and have googled myself to death. I am looking for the average price of a Craftsman Riding Mower -1975- current, Craftsman Walk-Behind Mower 1975-current, and a Craftsman Weed Eater 1975- current, does anyone have any suggestions as to where I could find this information?
