Here's my question: do you reach out to those people and educate them, showing them what the original (and public!) transaction looked like before their seller resold it to them? Do you educate them that they should really do their research? Because while some may see "opportunity" in buyers who are uneducated and are willing to pay ridiculous premiums on common items, I would feel terrible knowing that I took advantage of someone and so I refuse to raise my own prices. But I also feel bad watching others overpay! Should I just stay out of it, price my items as I see fair, and continue on my way without worrying about others? Let me know what you think. Thanks!
