As someone who use to go to every game and just buy re sell or scalp for tickets each game this is what I found for the home opener
Prices right now will be high
Most reasonable prices will come in June/July/leading up to training camp
Lowest price is always after a loss (even a pre season loss, which is kinda funny)
If you're cool with a price, pay it. Don't wait over what will amount to be maybe $30
