Used/cheap J-pop store in Los Angeles or San Francisco?

[Ayumi27]

Thanks for the advise! I tried the amazing coastline road (101 if i'm not wrong) but this time I gotta cross the boring-as-hell Route 5 if wanna arrive to Santa Monica by sunset

By the way... is there a wide variety of items in these stores? And what's the average price of an Ayu studio album, for example?

AND, are the SF stores WAY MORE expensive or just a few dollars more?
