With the tax,upper level sideline seats in rows 1-15 are $87 and upper level sideline rows 16-29 are $70.40.
Sneaky Snyder stopped including the tax in the face value of the tickets when he raised the ticket prices a few years ago. My seats went for $59 (with tax) to $64 (w/o tax), but $70.40 (w/ tax). I did not notice the price had gone up to $70 until I had looked at the invoice several times. I actually went to bed thinking my tickets had gone up to $64 and did not notice the extra line at the bottom of the invoice until the next day. IMHO, it's a lot of little stuff like this that tends to make the STHs dislike Snyder.
BTW, the tickets say $64 on them.
