This is a question of the ages.

I bought a pair of 1/4" female phono jacks, a 10k potentiometer and a small roll of #24 hookup wire there on Saturday.
I'm sure Target's inventory of electronic components and copper wire is rather thin.
I'm in Radio Shack maybe once a month to make a miscellaneous $10 purchase. I'm sure lots of other people are also. It adds up.
