How Much Does A Taylor Swift Concert T-Shirt Cost? (Only People Who've Been To A Taylor Swift Concert Please)?

Okay so I googled that question and people would guess how much and say what they thought it would be but I don't care how much you THINK they cost. I want people who've been to a Taylor Swift concert and bought a t-shirt there to answer. I went to a Britney Spears concert and got a $40 t-shirt there. Do you think it would be that much? I'm only bringing $55 to the concert on Thursday and I'm going to go to lunch at Olive Garden first so I want to know if I have enough for lunch and a shirt. Sorry to be rude about not wanting opinions but I just want to know. I've seen some people say they think the shirt would only be like $20. I doubt that very highly. I mean, the shirt will probably be between $30-$50 but I'm not sure. Thanks in advance; and I will pick a best answer. God bless. (: <3
