"G-Pass simply allows customers to worry less about getting into the venue and focus more on enjoying the event. And at the same time, it helps alleviate stress on box office partners," said Groupon vice president and general manager Greg Rudin in statement.
Groupon said the G-Pass has been used for consumers "to enjoy their favorite band, take in an off-Broadway show or cheer on the home team."
Out of the 1 million tickets sold, 700,000 of those were sold this year, which lead the company to say the G-Pass option was "gaining momentum."
The G-Pass option has sold tickets for events as varied as the Bon Jovi "Because We Can" tour, the Joffrey Ballet and Seattle Mariners ball games, the company said.
