Adafruit is awesome, but it's not remotely a replacement for a brick and mortar store. When I went to RadioShack in the early 90s I would pick the core part of what I wanted and then walk around the store visually matching parts to make sure things fit.
This is somewhat less necessary now that there are more standardized connections between things, but it's still nice and it's something Adafruit can't possibly replicate.
