I agree with the comments in Post 2.
People want to buy brand new items, like the ones you are selling, from properly registered business sellers.
If they buy from you, they have to pay the Buyer Protection Fee and they don't have the right to return their purchases for any reason.
I would look at your items and then, seeing it was a private account with no returns, I would look elsewhere.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
