(CNN) - Put down that checkbook: Mitt Romney's formal fund-raiser season is over.
Just over two weeks out from Election Day, the Republican presidential candidate held on Saturday night his final formal fund-raising event, spokesman Rick Gorka said.

Romney has attended fund-raisers from coast to coast - and even overseas in London and Israel - on his quest to win the White House. In total, he has raised more than $361.3 million this cycle, Federal Election Commission records through the end of September show.
Between fund-raising events in August, the candidate told reporters he would rather be on the campaign trail, but fund-raising would be essential to remain competitive with President Barack Obama. Through the end of September, Obama raised more than $567.4 million, according to FEC records.
"That's a challenge with a president who blew through the federal spending limits," Romney said. "It means that campaigns now have to spend a disproportionate amount of time fund-raising. You appreciate all the help you get, but you wish you could spend more time on the campaign trail."
Saturday's final fund-raisers - which included events at two separate locations for donors of different levels - were held at private homes and reporters were not allowed to attend.
The first half was held at the home of Dwight Schar, who is part owner of the Washington Redskins. The second half was at the home of billionaire investor Wilbur Ross.
Although he will no longer attend formal fund-raising events, the GOP candidate will continue to accept donations through his website, by mail and via text message.
His running mate, Rep. Paul Ryan, will hold fund-raising events this week.
