Where can I buy Polygon pol?

I'm curious, where exactly can I purchase Polygon (POL) tokens? Are there any specific exchanges or platforms that you would recommend for a first-time buyer? Are there any specific steps or precautions I should take when buying POL tokens? Additionally, are there any fees or commissions associated with the purchase, and if so, how do they compare to other cryptocurrency exchanges? Finally, is there anything else I should know before making my first POL purchase?
