Radio Shack is the only store that had mini-heatsinks when I needed them. It is the only store that had an ultrafine soldering needle when I needed it.. Also, a mono miniphone to rca adapter, a USB extension cable for less than $20, a 5-way cable splitter, an inexpensive AA-D-cell nimh battery charger, a cheap digital indoor/outdoor thermometer for my kegerator, 10W 1ohm resistors, etc etc etc
Don't say RS sucks. They have parts no one else carries locally.. Sure, you can order sh!t online if you plan everything a week in advance. I don't. I hope they stay around.
