Signing up for that site at the beginning is genuinely what I would do if I were do it over. Knowledge is power. Literally a $5000 learning curve for $99

Besides, my advice was to sign up, then ask for refund within the first 3 days after reading as much as you can. You get 3 days to do it. Then circle back to it once you need more info or advice

Seriously though, dropshipping is a dumb first business model to do if you're an internet marketing newbie.
