I had to do some grocery shopping while there--went to Ralphs and Albertson's, I believe.
You will have to take my word for this--but groceries were priced MUCH higher there than we pay in Texas. One little example--I buy jumbo sized eggs for 79 cents a dozen, at just about every store around here.
We definitely had culture shock when we moved to California from Tennessee. Everything was much more expensive here.
