Someone wants BIN but have already bid!

[OhCobblers]

does that make sense?
the one bidder i have now wants to BIN and they've accepted my price.
the option has now gone though as they'd already placed a bid - any ideas how i go about sorting it?

i'm guessing cancel their bid and relist with the BIN price included but they'll have to pay the BIN listing fee?!

any ideas? thanks!

I haven't done this but I believe you can choose to sell to current bidder at current price, then add the difference on the invoice.
Naughty (fee avoidance!) but seen it done a lot of times.

thanks for your reply.

ended up cancelling the listing and re-listing straight away (made sure they were online first!) with the BIN price but with the auction starting at 99p.

sold the item for a lot more than i expected so all well!
