Use cases:

  1. Some of your product have longer lead time. So you might need to let your customers know about that.

  2. Some of your products might have higher risk to be damaged during the shipping. So you will probably suggest your customers to choose specific shipping method.

  3. Some of your products might be on pre-order so you probably want to additionally warn the customers that their lead time is slightly different rather than for regular products.

  4. You might additionally ask for confirmation about the customer's age if the product is for adults only.

  5. You might want to show additional terms and conditions for specific products.

  6. You even might want to disallow the checkout for some products during the coldest days on winter to protect your customers from getting broken or frozen products.

  7. And much more!

Amazing, this is exactly what I need. Some of my products only ship Monday - Thursday and now I can notify my customers!


Works great! Makes my "pre-order" process easier without paying for any app! They also have great customer service, replied very quickly and checked the problem and answered with clarity, thank you for a great app


Fairly simple to set up, and it just works. It's been a godsend for making sure customers understand what they are buying, and to alert them when they need another item for full functionality. Sometimes customers are replacing one of the items so they're OK purchasing one and not the other, whereas other people may not realize one won't work without the other. So a big "Thank You" for a great app.

There is room for improvement, however. I wish there was a way to preview. I have some country-specific warnings enabled, and I'd love to see how it works. But since my IP address is not in those countries, I don't know how it appears to my customers.


What a fantastic free app it works perfectly


Just an outstanding free Shopify app. One of the best apps.


This is such a great, simple and versatile app. Very intuitive and does exactly what it claims. In our case, we sell some products that contain hazardous materials that require specialist shipping. This was such a simple and effective method to warn/advise the customer prior to checking out. Fantastic - we love it. Perfect in fact! Thanks so much.


App has been great! We have custom products or products that require special shipping and this app really helps us prevent customers adding those to the cart without customizing or contacting us for shipment details first - without making descriptions wordy, since it's in a convenient pop-up! Had trouble with pop-ups not showing for a bit and support team solved the issue very quickly. 5 stars!


Super easy! I use it to warn customers they are about to purchase a pre-order that is not available. It's a good work around due to Shopify Payments only holding pre-authorizations for 7 days. Would love if there was an ability to size the window, and have the customer be allowed to turn off the warning once they are aware of it, and wanted to continue ordering items from that group. As it is now, they have to see that pop up with every item they add that meets the requirements. Excellent, otherwise.


Does exactly what it says and helps to solve a very specific need for Trek Light Gear's site effortlessly. It means a lot to a small business owner when a simple but effective app like this is offered for free and to top it all off I had an issue with the app recently and got an immediate response and fix from the developer. Thank you!


Works exactly as it says, quick response to a query and had it fixed within minutes. Very happy with app thus far.
