Secondary market prices (buy low sell high)

In this video I talk about secondary market prices. And the issues people have when a knife goes for more then what it cost new. Imo the biggest thing to keep in mind is that you have a choice to buy the item or not. But I don’t think it’s fair to judge someone who’s looking to make a profit on a knife. He has almost certainly taken more losses them gains, and people seem to be fine when someone else is taking the loss. But when it comes to the buyer having to take a loss by paying more, that’s where people seems to have an issue.
