Ha ha, good luck with that. I never asked for an apology, but its nice that you offer one. I forgive you, but please do try to make valid points without resorting to insults.

Lets see.
You can't win if you don't play.
You lose if you play.

I guess there is no way out of this delima.  :D

Where do you get resistors for less than one cent each? I get them cheap on the internet, and they are 2-5 cents each, in packs of 100 or more.


Pretty much anywhere. Here's some 10K resistors from DigiKey for 0.2 cents each at qty 100:

As an aside, this is easily my favorite thread of the new year.

Not one mention of Sparkfun's place in all of this yet (OP's example was written by a Sparkfun employee).

Sparkfun did sell a no-resistor-multiplexed-led display, their 7 segment serial display. They updated it. Spot the difference ;)

Your goal is noble.

However, at some point, you have to recognize an individual's right to remained challenged.

It makes you happier, and it makes the people who refused your help happier too.

Win-win.
