The Art of the deal

What has happened to the art of the deal? We had a yard sale today to get rid of stuff that was clogging our basement and to make some extra cash. We priced most of the big stuff as one would do. Now when I used to go to flea markets and yard sales with my mom and grandfather I use to watch them bargain for most of the things they purchased. Today though not one person tried to bargain down my prices, they would look at or ask the price and walk away. Now I know that I didn’t price my stuff to high but hey I was ready to bargain but nothing…..So my question is what happened to the art of the deal?
