Ticket advice

So my wife and I will be in Nola during week 2 because she has a conference to attend. What better time for us to one again see our beloved Saints in person for the 1st time in about 5 years. Home opener vs Tampa could be a hot ticket so any advice on where to get the best deal? Here, stubhub, nfl ticket exchange?

Thanks in advance, looking forward to being back.
Buy them the morning of the game off the ticket exchange or stub hub for the cheapest price.
