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.

I am setting up a new website and looking to integrate the Shopify buy button as the payment integration gateway. Its a little complicated and your support is hard to reach because you have to dig through forums, saying you cant find your answer before it finally allows you to get the support phone number or chat. I like having the option of the buy button because I want to use wordpress to customize my website, so I really happy to have the option but setup with containers and stuff is just a learning curve I have to get used to.

It worked just how I needed it to. I emailed select subscribers and allowed them the opportunity to an “exclusive pre-sale” So it wasn’t available on my main site just to the customers I sent it to. Worked really well! Just wish it showed the product description.

Great but I would like to see this embedded within an email campaign like Mail Chimp where I can paste the html code within the email. Also where consumers can adjust quantity of the product when it is in the cart

The app works well but like others have said, there are some limitations. It would be really great if it worked with other apps, like Easy Tabs, so that you can tab the descriptions (this function doesn't carry across to the Buy Button).

That is really a great option for us to enable our own store with help of shopify. It would be an excellent if we could have more options altogether. For example:
1. More customization 2. Image size in percentage (sometimes it shows so big on page)
3. Once payment is done, back to button to reach to store is missing
4. Rating / feedback option is missing
5. There should be 2 buttons, one for view product and another for add to cart (or once we click on product image, product description page should open)

It's pretty easy to set up and install by and large. I like how seamless it integrates on both mobile and desktop. I wish there was some general embeds for, say, a shopping cart to be on all page and not just where an embed lives (rather than having to piece code together for this purpose). In addition the load times can be quite long – around 8 seconds, and it doesn't seem to cache well. But all things considered it is a really wonderful feature.

A great alternative to a full Shopify store, as the control over my own web hosting website is important. I like that the features are mostly in line with the full website plan- however there are some things that could be improved. The customization of the button is quite stripped down. There could easily be more features added, but I feel like shopify wants you to buy the full plan instead. Also, a lot of addons dont support the Buy Button and I wish this wasn't the case. It should be as easily integrated as the store but its not. Overall 4/5

Very good for embedding products in an external website page. I use it with collections so i'm able to sell different type of products under the same shopify account. 4 stars because when I choose the 'view product' option, instead of add to cart or buy now, the images should be clickable too. It's annoying especially on mobile devices where one wants to tap on the image intuitively. Would be nice if you could change your code so that it works like that. Many thanks.

We use the buy button and we would really like to have a dashboard for this (which buttons are used where and how they perform). Currently you can only create the buttons.
