Buy Button channel , 362 reviews
Overall a great app, easy to use, works as designed. Would love to have an option to display a throbber while it's loading on the install site. Seems to be slow loading more often than not. Leaving customers wondering if the page is blank.
It appears Shopify has largely updated the Buy Buttons, because I see none of the problems people are citing here. The Buy buttons are now customizable in color, as is the text, as is the description of your products (done from your main Shopify site which then shows up in the Buy Button cart). You can embed one item, or an entire collection or stuff. And customers can return to your site by just clicking outside the cart to add more items to the cart, and then checkout in one transaction for everything.
What I dont see always working is the free shipping over a certain threshold. Perhaps I need to play with the settings some more. (it runs off the settings in your main shopify acct even if the buy buttons are placed on another site)
But the product does work and for what it is designed for it does well. People that need a full featured cart should realize this is a more limited pop-up cart for another website, it will sell products but for tons of customization you should probably use Shopify's full site. It still offers a complete checkout, coupons, and shipping options so for as small as it is it does alot. This is a pretty good product and I dont know of one other company that offers a similar product.
