Cost of Delivery with Blue Shield PPO

We're planning to start trying for our second child. Our first was born at Kaiser, but we've since changed health insurance and have Blue Shield PPO with a 20% co-insurance. 

Would anyone be willing to share what hospital costs have been like recently - and where you delivered? I'm curious about various types of deliveries.  My first was an unplanned C-section so while I'm hoping for a VBAC, I'm mentally (and financially) preparing for another C-section. Thank you!
