PROMO-SOLS

Great app! To my knowledge it is the only app that does what it does. The support is very quick and reactive. I searched for quite some time how to display tax included & tax excluded prices. I was ready to hire a developer and have it custom made when I discovered the app. I'd highly encourage you to check it out.

I used this app to create a popup to gather a mailing list. It works very well, and we later changed it to encourage customers to reach out to us if they have questions.
