It's apparently super common in Indonesia to have WhatsApp button on the website. In many popular websites, the Checkout button even opens WhatsApp (purchase happens in a WhatsApp chat, payment using bank transfer). It could be cultural, so maybe I'll region-lock the button. I wonder how's things in other countries?
I don't have time yet to implement payment (maybe just use WhatsApp lol), that's why I don't put pricing. Is it common to put something like "This is free but later I'm going to charge you $x"?
For the AI image, point taken. I will update it once I have some nice shots.
