Home visiting and looking for cheap CA themed souvenirs to bring back

As the title states, I'm home for my yearly visit and I'm looking for somewhere I can find cheap CA or Bay Area themed gifts. I used to see little souvenirs at the dollar tree but I have stopped by a few and haven't found anything.

Airport is outrageously overpriced, I'm not trying to break the bank to buy a t-shirt and a few fridge magnets ya know? Any recs for where to find some small, affordable gifts? Tia!
