Spoiler-free eras tour?

Has anyone else gone to an eras show and avoided spoilers? I’ve avoided looking at set lists and consuming eras media, I want to be fully surprised come November when I go, but I’m worried that there’s things I’ll miss out on like basic things that others are doing like how to handle the merch lines (what is even exclusive to shows) or whatever the friendship bracelet thing is (it seems cool but, again, I have avoided a lot of that content so I don’t know what to expect on those either).

Did anyone else attempt spoiler free? How was it for you? Any tips? Please keep answers spoiler free, too!

Further context: been a standard fan for a long time but this is my first concert of hers
