Eric Church had already delivered a fair warning to those who purchase tickets to his Holdin’ My Own Tour through the secondary market.

He's now followed through on that promise by canceling 25,000 tickets purchased by scalpers. More than 2,000 of those scalped tickets were for his two-night stand in Nashville starting May 26.

All shows that remain on his tour, with the exception of the April 22 stop at Cincinnati’s US Bank Arena, have been affected.

Fans are encouraged to purchase tickets directly from his official website so all purchases are made at face value. In addition to ensuring that fans aren't paying inflated prices, Church urges avoiding the secondary market because it’s likely that tickets sold by secondary brokers will be invalid by the time the show happens.

When the tour was announced in August 2016, Church revealed he commissioned a proprietary technology that scrubs ticket purchases using up to 10 different data points and automatically flags orders made by scalpers. Orders may be cancelled at any time and without warning.

“Orders that we cancelled were automatically refunded to the purchaser’s credit card,” a spokesperson from Church's management said in a statement to CMT.com. “Ticket scalpers got their money back, and we would expect that scalpers would in turn refund their customers. But with ticket scalpers, you never know! Fans would have a strong case for contesting charges with their credit card company if they paid for something that the scalper didn’t deliver.

“We hope that fans who are in this situation will be able to buy face value tickets from the venue’s official website when we release the tickets. That’s why we give fans a heads up as to the exact time we are going to do it.”
