Checkout Widget

Checkout widget I'm working on for a checkout-as-a-service side project.

I've been using Stripe Checkout to sell a course of mine for a while, but I need to start properly collecting Canadian sales tax, so thought I would build something that solves my problem and is reusable for future projects.

My friend Steve had this nice banner image for his Heroicons project, so I've been shamelessly using it for seed data :)

I'm primarily a backend developer (certainly never had designer in my job title), but trying to learn so would love any feedback.
