So many deals to be had along U.S. 127 shoppers will drop cash on just about anything.

For the last 15 years, the "Mt. Carmel Girls" have traveled all the way from Jasper, Alabama in their matching shirts.

The group of friends went yard to yard and have traveled all the way to Kentucky one year. That’s why they made matching shirts.

"We didn't want to lose each other to start with, and so we can keep up with each other,” they explained.

The sale began in 1987 to encourage people to take scenic routes and travel through smaller communities.  Today it’s evolved into more than just a yard sale.

Vendors said people from around the world stop by to shop, say hello, and visit their communities.

"When it's all said and done you make a few dollars, but the experiences is worth more than the dollars, Mike Kaufman, vendor said.

For 12-year-old Sam Sonksen, it's the thrill of the sale.

"I start by asking for full price and then go down two dollars,” Sonksen said.

For others negotiating a good bargain is part of the experience, but all about the journey along the way.

The yard sale runs from August 4th to 7th along U.S. 127.
