Yeah, I just kinda flipped for a sec there. It's possible that there were far more than just a thousand a day. Also note, the weird model number. It's possible they made different models on the same day, and I would expect the serial numbers to be sequential starting from one for each model number.
Then I exclaimed "How many of these are there?!" and I realized that's why I'm able to get them so cheaply now. Solely because there are so few of us who care about these, and because there are so many that they're that cheap. Even with all the ones that apparently end up getting tossed in favor of... new rubber domes.
I think I need to cue ripster to post the supply demand curve, because that's a very blatant case.
Why the comment about not knowing what PLT means?
