This app is exactly what we needed for our Prop65 California warning. We reached out to get some help and they quickly were able to do exactly what we needed - thank you so much!!!

This was perfect to notify customers that order fulfillment was going to be delayed when they added products to their cart.

One Less Car Shop

So far so good, easy and straightforward to set up. Warnings can appear in multiple places which is handy. I haven't yet had a chance to test all the options.

Mexicali Blues

This app does exactly what it says it will do and is quick and easy to set up.
I love that I can use the same warning for multiple products or that I can setup unique warnings as necessary.
Our returns have decreased significantly since we began using this tool.
Furthermore, I have support, when needed, to be thorough and fast.


The support for the app is really great, with quick replies. The app is easy to use and very convenient.

I use this app to make sure people select the right t-shirt size on my site, works really well and the app support has been great.

Moruga Cacao

Great customer service, great app. We use it to communicate our current move to a larger fulfilment partner and the connected delay in shipments.
