Buy Button channel

Button works quite easily BUT it would be a HUGE improvement if Shopify could enable the following: 1) ability to add campaign tags or a simple way of knowing where specific orders are coming from (since we use the buy button on different campaign pages but they all appear as generic Buy Button purchases); and 2) the ability to automatically apply a discount or free shipping for each button that is generated to make promos on landing pages more seamless and less friction for the customer (who currently needs to add the code manually).

Brilliant button! A clever and very simple app to use and has allowed me to change the e-commerce payment options on my current website without having to design a whole new website. Delighted - Shopify really is brilliant - at some stage I will move over to this platform entirely.

Easy to use and select products I want to offer. The code was easy to apply to my affiliate's website.

It is a very nice solution for people who already have a website and want an easy system to deal with sales. Also, very affordable and super easy to integrate. I use it with WordPress, and I like the interface a lot. It would be nice if, in the future, it becomes compatible with the plugin "WPBakery Page Builder," which I use to build my WordPress. I needed to create a new page without using my building plugin so it could work.

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.

Really needs the script to keep the cart on every page once products are added, as well as ability to mask URL change.

Loved the convenience of the buy button for my customer! It allowed easy access for the customer to buy the item we were emailing about.

Buy Buttons are great for business, but slow to process payments.
Square Payments pays in 24 hours.

I have used this app to help sell individual catalogs on separate brand sites apart from Shopify. I use Shopify to keep track of all the overall sales but the Buy Button allows me to sell where I want to sell.

This is a pretty great solution for adding a shopping cart however it could benefit from a bit more customization, most notably an area for advanced users to implement custom CSS to help match the style, padding, fonts, etc of the site it's being embedded in.
