Contacted Res Centre re 'buy it now"(BIN).
1/ BIN with PayPal(PP) introduced to cover sellers from dodgy buyers.
2/ BIN without PP,buyer "may have their own reasons" as to why they do not pay immediately... and ....the buyer is misusing the BIN feature by doing so, does knowingly misusing the BIN mean dishonesty..yes.
3/ eBay advises all to inspect where possible before sale,so do I.
Decided to put my boat back on once more WITH PP.
Guess what, 3 offers and no dishonest manipulation of the BIN by ending the sale and blocking honest bidders/eBayers.
