How many times has this happened to you: You have bought a product, but it turns out you have no use for it after all. Thus you would like to sell it to a friend or acquaintance. The product is completely unused, unopened in its original package, and exactly like new, and you have the receipt and possible warranty papers. Yet no acquaintance is willing to pay the full original price for it. They always want a significant price reduction.
This seems to be a very strange instinct that 99% of people have, and I suspect that in one form or another it's something that corporations have in one way or another succeeded in implanting into people's minds. Or, at the very least, are very happy about.
For some reason this instinct is so strong, that most people would prefer to buy the product directly from the shop than from a friend, unless they get a price reduction, even though this makes absolutely no logical sense.
It doesn't matter if the product is completely unused, even unopened, in its original package, and exactly like it is when you buy it in the shop, and you have the receipt and any possible warranty papers that might have come with the product. They still want the price reduction, or they prefer to buy it from the shop rather than from you.
There is no excuse that makes sense. If the product turns out to be defective, they can simply go to the shop for a replacement, given that they have the original receipt/warranty. There is not even any kind of theoretical loss that they could suffer. And yet, most people would never pay the original price, if it's not directly to the shop.
It makes no sense.
