I'm a member of a few groups/sites with both collectors and dealers. We sell, we buy, we comment, the usual. Whenever I list items for sale, I list for prices that I would be willing to pay myself, I keep it fair. But recently what I have noticed is times when items are purchased from me, and are then resold or auctioned off to people who are paying or bidding much more than the item is purchased for from me. And before we start talking about "well what an item is worth is different for everyone", or "maybe you're selling too low", I am literally talking about how people could go to ebay and BIN the same item for 2x-5x less than what they are paying during that resale. 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!
