Don't try to give anything away for free. I once had a perfectly good laundry tub that DH was adamant that we get rid of. I put a free sign on it. One gentleman really wanted it but wanted to know what was wrong with it because it was free. After a lengthy discussion, I wasn't able to give it to him, so I said "Okay, I'll take $1 for it." He bought it. LOL
Hope it's successful for you!
