Offers are a mess since the introduction of the Buyers Protection Fee.
I was looking at an item yesterday that I have set to accept offers of £16.
An offer of £16 had been declined and there is no way to identify the interested buyer.
I assume they needed to actually offer £16 + BPF for the offer to be accepted so, they needed to offer £17.36.
As advised, reduce the price, bult allow for the BPF.
"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)
