Herzberg Design Co review for Buy Button channel

Switching from the default Squarespace Digital Downloads store to the Shopify Buy Button has been great, except for one thing. The great: it works smoothly along with digital downloads product variations, so I am now able to sell dozens of variations of my products, a feature I really needed. What's unfortunate is that there is still no way to add a custom field to the checkout for the Buy button, even though there's posts as old as 2016 saying that its being worked on. With that feature added, it'd be 5 stars from me.
