There may have been more customers come in because of the novel effort to promote local businesses, said owner Erica Caldwell, but only five people said specifically that they came in because of the "cash mob."

"I know some of them hadn't been in the store before and I think it's fantastic if it gets people to visit a store they hadn't been in before," Caldwell said.

It's hard to say, said Caldwell, if the business day was bigger than normal.

"There is no normal," she said. "Business fluctuates so much day to day, there is no baseline to compare it to."

But that's almost beside the point, Caldwell indicated.

The key of the Genesee Cash Mob idea is to promote the idea of shopping locally at independently owned businesses, which Caldwell fully supports.

"It was definitely worth it," Caldwell said.

And she figures being the first cash mob effort, the participation will only grow. She didn't have high expectations for a big return, being the business selected for the first week.

"It was wonderful being the first business selected," Caldwell said. "I'm very proud of that because it means we must be doing something right."

It is "Genesee Cash Mob" day at Present Tense Books, on the corner of State and Washington.

The event, organized by Chris Charvella, is designed to encourage local residents to shop at local businesses. Each week -- this is the first week -- people nominate a local business to support for the day by spending at least $10 at the store. Present Tense won the first-round voting.
