Where do they sell Hex Axle tool (non-online)

I am wondering where I can get hex axle tool in store. So Cal to be exact, because i been looking for it and none of the possible place have it. I know this one giant dealer Berts Mega Mall has it but they sell it for so much more expensive than online. I am trying to look for price similar to online, but I can get it right away rather than waiting for a week or so.
