Does anyone know a good place to find refrigerator magnets?

When I was in San Diego a few years ago, I found a cute shop in Seaport Village that sold refrigerator magnets. I collect these, so I bought a few and took them back to my apartment in Pittsburgh. Unfortunately, they got lost in the move to upstate NY. I’ll be going back to San Diego soon, but I don’t remember the name of the shop. Can anyone give me a hand?

Alternatively, if anyone knows of stores like this on the East Coast, that would be helpful, too…
