Should I buy tickets online or can I buy them at the door?

It depends on the event. For big concerts, festivals, or known-name acts, buy ahead — they often sell out online first. For smaller venues like local shows, museums, or theater companies, walking up is usually fine and they may prefer it to skip fees. Check the event’s website an hour before: if tickets are still available online, they’ll be at the door; if sold out, don’t bother going.
