Where can I get a $2 bill?

Excuse me, I was wondering if you could help me with a question. I'm trying to find out where I can get my hands on a $2 bill. I've heard they're still in circulation, but I've never actually seen one in person. Do you know of any banks or financial institutions that might still have them available? Or perhaps there's a specific place I should be looking? I'd really appreciate any information you could provide. Thank you in advance for your help.
