By definition, a Pay-Per View event would be defined as a one time special event, such as a Concert, wresting, MMA, or Championship Boxing. Here are known ways:
1.) Search for the event in your onscreen guide.
2,) Search for an event using the Spectrum app.
3.) Search for an event using Spectrum's website.
4.) You can order through your box remote, on-line, or by calling Spectrum. I believe that if you place your order with a Spectrum CSR, there is a $5.00 service charge.
