Cash mob's have been popping up all over the country and yesterday was Omaha's first at The Bookworm on Pacific Street in Omaha.

The Omaha World-Herlald reported that more than 200 cash mobs have been held around the country over the past year.

Cash mobs are similar to flash mobs, but they encourage people to support local businesses by pledging to spend $20 on a chosen day.
