I have a couple at the moment.
1. It would be great to have more payment options. Here in Brazil its very hard to get USD credit card, and I am in good "standing" I only managed to get a pre-paid one which I use for USD purchases, and it was bureaucratic. I often pay using this merchant AstroPay, mega cloud uses them and a lot of other international companies that sell in Brazil.
2. There was no error message when I forgot to digit the date and cvc code for my card while purchasing a subscription. It wasn't until I saw the there were no numbers there but rather the text indicating MM/DD/CVC that I figured it out, completed the form and made the purchase.
Happened on Chrome - Version 114.0.5735.110 (Official Build) (64-bit) if that helps.
But other that, congrats on the site, I like it!
