If you order tickets online do to get the tickets through email, or pick up at theater?

Agreed, I've never needed to order online.

Yeah, i wouldn't bother with online. You shouldn't have any problems getting tickets there.

We always pick him up at the theater

Never ordered online. Lines are short. Less than 3 minutes usually.

i do on card

You can, but buy them at the door to avoid the "convenience" fee from the third party vendors like fandango. Unless you are trying to buy a popular ticket from one of the old movie showings. It'll never be a problem.
