Stubhub is convenient to find seats... But having the owner transfer the tickets via BYU is the only way to guarantee legit tickets.
1. Find on KSL classifieds or craigslist.
2. Pay via paypal (Never send as gift) or other disputable payment .
3. Only accept ticket via BYU online transfer.
Stubhub has fraud, but most stubhub ticket issues are sellers mistakenly uploading the wrong tickets.
I use stubhub and rarely have problems, but I never know if the tickets work until at the gate when its scanned.
