So far so good, we'll use it to display warning messages for shipping delays during the holiday season.

Great app to manage warnings on some products. I use it for product delays and clients understand it perfectly.

We are using this app for informing our customers about products that are sold out momentarily - to give them relevant information and thus making them stay in the shop - not losing the sale. We can really recommend this app :)

Very easy to use, easy to set up, and Customer Support was quick acting and proactive in helping us set these warnings! UPDATE 1/8/21 - Customer service continues to be SUPER helpful getting our concerns addressed and corrected. Couldn't recommend this app higher!

We are starting to use this app to remind customers of certain delivery instructions. We really like how easy it is to implement and for our customers to visualize. We are still trying it out, so far so good. We'll see how it goes-.

Wonderful app and huge time saver! The support team has been quick and very professional. Highly recommended! Best variant level tagging/warnings on shopify!

Works great! You just need to determine the correct tags/class for your buttons to get it to function anywhere you like! Was able to get it working in unison with other apps that add additional 'add to cart' options as well.

Thank you for the feedback first of all. The app actually is able to work with the "Buy now" buttons as well. In your case that was a button built by another app, but we've adjusted the app settings in order to cover this button as well. Now it should work! :)
