Yes.

You open unpaid item cases for any such scenario.

4 days after sale date, open an unpaid item case.

That gives the buyer a further 4 days to pay or arrange pick up and pay cash.

If no response, close the case. You get your fee back, buyer gets a well deserved strike and you are free to relist.

Then add the buyer to your blocked bidders list and set blocks on your account if you haven't already to prevent those with strikes from buying on your account.

Neither party can leave feedback after that.
