I JUST WANT TO BUY THE BUNDLE WITH MY CREDIT CARD AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
There isn't much I can do on my end. But you should be able to set up either a credit card or Paypal account support in your Itch io account settings.
Maybe I just need to wait for the bundle to expire.
Please try again, I made an account with another payment provider, and it might fix the issue for you.
It worked! Thank you!
