As if the S.F. Giants making the World Series weren't exciting enough, here's an offer for all you fans in the Bay Area. A Jamba Juice insider has confirmed that those who show up wearing S.F. Giants apparel will receive 20% off their order.
This offer is limited to locations in the Bay Area, but I'm not sure how far that extends, so call ahead to confirm that your local Jamba Juice is participating.
