The Ringling Brothers is coming to town. Goldstar has tickets from $10.50-$18.50 for the Oakland show, August 15-19 it will be in Oakland. August 21-26 it will be in San Jose ($11-$19.90), and August 29-September 2 it will be in Daly City (Cow Palace) - Goldstar tickets are $12-$19.50 for those shows on Goldstar (and higher elsewhere).
It's probably too late for this show, but you can sign up with them and get a free ticket for your baby 12 months and younger. However the Goldstar site says that lap children age 1 and under don't even need a ticket, so maybe it's not such a deal after all!
A Chorus Line is playing in Oakland. Not appropriate for all ages, of course, I took my daughter this year (when she was 11) and she loved it, giggling at a few of the lyrics. Tickets are available August 9-18 on Goldstar for $14.50-$23.
Aquarium of the Bay is offering some deals on Goldstar. Get tickets for $6.48-$11 instead of $13-$22. There is a $3 service fee, but even with that you'll save a $3-9 dollars per ticket. The aquarium is at Pier 39.
If you like circuses, Circus Vargas is coming to San Jose in September. Tickets on Goldstar are $12.50-$17.50 (half off).
The Tech Museum of Innovation in San Jose continues to offer discounted tickets for $7.50 (weekdays) and $10 (weekends) on Goldstar ($15 retail). We love this place! Even with the $3 service fee, you will still come out ahead.
Roller derby (this is our review)! This is our new favorite sport. For $11 (half off) you guys will have a fabulous evening watching women roll around the rink, elbow each other and race for first place, all while dressed in funky clothes. See the Bay Bombers in action in San Jose. Get tickets here for August matches in Santa Clara, and here for September matches in Santa Cruz.
