I probably wouldn't be one of your favorite yard sales then. I had one years ago before moving down to Mexico and most of the stuff on sale was in excellent condition and priced very low to move quickly. I didn't want to have an all day sale and in the ad in the paper I mentioned that the yard sale was only from 9:00AM to noon and featured some great audio gear at cheap prices. Wasn't trying to make a bunch of money - just selling the stuff I wasn't going to take with me and figured that somebody who could use it would be willing to pay a few bucks for the privilege. I even provided a power cord and small speakers to hook up to demonstrate that the audio gear all worked. Most of the stuff was going very quickly but a few people asked the question, what time I was closing? I told them at 12:00 and what hadn't sold by then was going to the American Cancer Society Thrift Store - no exceptions. I also mentioned that if they really wanted it they should grab it now.
Sure enough, these guys show up at 12:15. Watching me stow the few remaining items back into the garage the one guy sees the Pioneer CTF9191 deck that I had priced at $20 still there in addition to an old pair of large Acoustic Research speakers that were in great shape and priced at only $45 for the pair. He asks if he can just take them since I was going to donate them. I told him no, the sale was over. He pleaded and again, I said no. He offered me $25 for them both and again I turned him down. Upset by now he finally broke down and offers to pay the price I had them marked at. I looked at them, looked back at him and said I would like to but I had made a commitment to the folks at the Thrift Store and meant to keep it. I closed the garage door and told him to go by the Thrift Store to see what kind of deal he could cut if they were still there next week.
He was soooo pissed. I was amazed that somebody could risk passing up a perfectly working CTF9191 and a very nice pair of AR's to try to come back later and save a few bucks.
