Where can I buy Sats Ordinals?

Excuse me, I'm quite interested in investing in the emerging cryptocurrency market, and specifically, I've been hearing a lot about Sats Ordinals. Could you please enlighten me on where I can purchase them? I've been doing some research but haven't found a clear answer yet. Are they available on major cryptocurrency exchanges? Or are there specific platforms or marketplaces dedicated to trading Sats Ordinals? Additionally, are there any prerequisites or qualifications I need to meet before making a purchase? Thank you for your assistance in this matter.
