I hardly ever go to the scrapyard maybe once or twice in the last five years but recently I had a friend of mine that works in HVAC ask me to clear out his backyard which had about eight units old but complete units about 15 air handlers! So I loaded them all up took him to the scrapyard. They paid me $847.26 but they only gave me $87 in cash and told me they would send me a check in the mail. Is this normal Is there something I did
