Where can I buy Ordinals?

Excuse me, I'm a bit new to the cryptocurrency scene and I've been hearing a lot about Ordinals recently. Could you possibly elaborate on where I might be able to purchase some? I've tried searching online but there seems to be a lot of conflicting information out there. Are there any specific exchanges or platforms that you would recommend? Additionally, are there any safety measures I should be aware of before making such a purchase? Your guidance would be greatly appreciated.
