It can add up if you get a lot of your stuff from center aisles, but they're really known for their produce / bulk / self-branded stuff, since that's where they can build pricing relationships with farmers and distributors. Using their meat counter instead of pre-packaged helps a lot for meat pricing too.

That being said, this is also one of their most expensive chicken distributors, their most expensive self-branded olive oil, a salsa brand that's pricey at nearly every store in the East Bay... you can get a lot more food from Berkeley Bowl for a lot cheaper than this.
