I did a quick 15 min search...

I did not find any listings for Margo’s or Buckeye in Redding (I really didn’t look too hard though)so I figured it was probably in another town?
The Margo’s chips were sent to Redding, Ca but I believe they were used in the town of Buckeye...which is in Shasta County. They were sent to Redding because the post office discontinued service in 1943.
The town of Buckeye was a mining town from the 1850’s

My best guess...the Club was named Margo’s (I don’t know who owned it...yet) and it was in the town of Buckeye (which is in Shasta County...like Redding) and the chips were sent to Redding because the Town of Buckeye didn’t have postal service. I don’t know what that address was...could be Margo’s home? I will continue to look
