www.allstarcardsinc.com will let you view their catalog
All Star is not set up for a retail setting, as 99.9% of their business is mail-order via catalog. I have never had a problem of walking in, looking at their catalog, and making a purchase though.
Having lived in LA and in Overland Park, I have been to each location, and they're all very good, with excellent selections in post war.
