I'm not sure I understand the above statement. Perhaps you could expound upon it further.
Given this example: an item that you could flip for, say, $300, does the above statement mean:
- If you offer them $20, that is wrong and unethical and you are ripping them off?
- If you offer them $100 (which is 1/3 of $300), that is acceptable and ethical and it's a decent deal for both parties?
- If you offer them more than $100, you are giving them a good deal?
Based on that, apparently it just a matter of where you draw the 'line'. What is magic about 1/3?
The fact is that there are many lines in life, and nobody has ultimate knowledge to know where they all are. Everybody (buyer and seller) sets their own lines.
