Heck, why stop there....
1. Skip your vacations, instead watch a destination YouTube video
2. Sell that car, and bike/walk everywhere
3. Avoid eating out, instead cook every meal
Your choice, but let's not act like the prices are "out of control". 15% increase for me as a STH, which is well below the NFL norm.
The last couple years, I go to half the games and the profit from selling the remainder, make the math basically a wash (less gas). With a strong team, that equation will continue to work at the new stadium- but that's not at all what I care about. Just pointing out, the "actual cost" even with the PSL, isn't out of control
