I don't really like buying games from secondary sites like that. 

I'm putting in all my card information correctly, I've checked many times.
It's a Money Network card through McDonald's whom I work for.

Is it maybe because it's technically a pre-paid card? I cannot link it to my CashApp account due to that reason.

I refuse to make a PayPal account for issues I've had with them in the past, and I currently have no way of taking money off the card and putting it onto another.
