A flash mob is a group of people assembled in one place for a specific purpose.
Buckhannon is taking it a step further with "cash mobs".
The Buckhannon-Upshur Chamber of Commerce said cash mobs are flash sales that boost sales and supports business.
It will hold a cash mob from 8 a.m. to 2 p.m. Wednesday at the Farmer's Market in Jawbone Park.
They are encouraging people to spend $20 on fresh vegetables for their Fourth of July weekend cookouts.
