I have bought all my tickets on the secondary market.
Stubhub, Seat Geek to buy right now and they are legit. Ive used ebay and never been swindled. Pay with a credit card so you can decline charges if something were to go wrong. I have also used craigslist without issue, but in this case dont look there unless all avenues are exhausted.
If youre willing to hold out until game week, prices will come down. Ticketmaster receives all returned tickets from the teams on Wednesday, but check earlier for good measure. Some good seats too, not up there with the sea gulls. I have found that Ticketmaster prices are lower.
Tickets are always available. Funerals come up and people have unexpected events that change their plans to attend the game. If you do buy from an individual, take a pic of their drivers licence. If an individual seller drags their personal problem into the transaction walk away because its likely a scam.
I am looking for 2 tickets. If I run across 3 I will sell you 1 at the price I paid. But I need US money and not pounds
