Round Rock’s second Cash Mob, where customers arrive en masse with $20 to spend to support a local business, will drop at 11:30 a.m. Saturday, Sept. 15, at The Book Spot, 1205 Round Rock Ave. (next to Round Rock High School.)

Four local authors will be at the shop talking about their books: Mary Beth Bruton, Rick Foster, Lester Morris and Rick Foster.

Door prizes will include gift certificates to local restaurants (Hoody's, Niki's Pizza, Johnny T's BBQ), The Book Spot and Kaleidoscope Toys.  

Community Impact is sponsoring the event, which is being organized by the Shop the Rock program co-sponsored by the City of Round Rock and the Round Rock Chamber of Commerce.
