Since I have retired, I spend a lot of time going to indoor and outdoor swap meets on weekends. I usually look for antiques or collectibles, and sometimes I find a really good bargain when the seller has no idea what something is really worth. I can usually do a lot more haggling at swap meets than I can at antique malls. The biggest problem is getting it all back home and finding a place to store it.
Sometimes my wife will go with me to these swap meets, and she'll usually buy fresh produce from local farmers and paperback books.
