My simple google search tells me its a large LBS that sells GIant, Felt, Raleigh and Diamondback

BicycleWarehouse.com - Largest Bicycle Retailer in San Diego - Locations in San Diego and Temecula

Bicycle Warehouse - Temecula, CA | Yelp

Their advertised prices don't look any different than any LBS by me so I certainly wouldn't make the drive from LA. But if it's closer to where you live you might feel otherwise
