bought it a short while ago please tell me there's a code you are using for that wonderful checkout. email-->entering postal code --> entering card --> done. any reason why you are capturing postal code first? I will post another comment with a review later is this built using electron? where can you find a boiler template project complete with installation wizard? edit: just realized you can't even import HTML files…
Stripe also has the same thing: https://stripe.com/checkout
