Thank you so much! – Sorry you are unable to purchase it with credit card.
I recently switched to direct payout, instead of collection by Itch.
(I was tired of waiting 1-3 months to get paid by Itch)
However I didn't realize this would disable credit card payments until I connect Stripe to my shop.
I will try and get it setup and working this week.
Thank you for letting me know and thank you for your support!
