Time Waster
When it comes to buying and selling things online, you must be willing to negotiate. There are, however, some people that go overboard with the concept of bargaining. You can’t forget that just because something is used doesn’t mean its value has decreased.

Offering the product for free is a little like demanding that the item be given away for no cost. The seller does not become upset; instead, he gives him another discount, and the person asking becomes highly argumentative. And this individual over here appears to have completely forgotten about it.
