I have to say, this cuts deep. I've sold all my chips at a fair market price. Because the market value is a price agreed on. When buying something, I don't think I've ever asked a seller, "how much did you pay for what I am trying to buy?" and "how hard was it to obtain what I am trying to buy?" and then factor that into a new deal I'm trying to make. those two things are pretty much irrelevant.
I commend you for doing the leg work and selling them at cost. You are basically taking a $250 item and gifting it to another member for only $100. That is very nice of you. Charitable work. My wife and I donate to charities often, but never once have I thought that I should donate, or gift, my hard earned money to upper/middle class chip collectors. I'd rather help food banks and animal shelters. So if I own near mint THC chips, I am going to make an appropriate ask, regardless of where or how I got them, and how much they cost me.
Sorry, I just had to share my opinion because I read through this thread and it got me really depressed. Since reading this thread, two other members have messaged me for Paris chips, and the first sentence in my response, was check with danny first or try to find them cheaper if you can. I'll continue to do that if you generous chippers have some to spare.
