Best Marketplaces to buy single sports cards

For over 40 years, it would be an understatement that I have been passionately collecting sports cards. I generally buy single cards for one of these use cases:
- To add to my personal collection
- To get the card signed by a player (using SportsCollectors.net)
- As an investment / To flip for profit (using Collectz)
So I thought it would be fun to share some guidance around what places I go to look when I am searching for specific single cards.
