San Francisco area - where 2 buy low price satellite parts?

[37_46x122_26]

I'm in need of a rg-6 grounding block connector and clamp.

RadioShack's prices increase by the minute.
It's a 10 mile drive to Home Depot or Lowe's.

Any suggestions for a shop near South San Francisco with normal prices ?
