[dutchinboys]

I have a bid placed on an item i have for sale.

The bidder is from a country I donnot ship to.

Can I cancel the auction now.

You can end the auction but a better option is to cancel the bid and block them from bidding.

Then set your buyer requirements to block buyers from countries you don't ship to.

All of these processes are explained here.
