Discount Ninja Promo Engine

This app is intuitive as Shopify apps go, but the shining star of the entire experience was Bart, who went out of his way to help me with an issue on my store. He is a tremendous asset to this app. The pricing discounts are also very deep and varied, it will help you to make better discounts, for sure.

Discount Ninja is game changing.

Stacking codes.
Discount summary display.
Cross-sells and Upsells at add-to-cart (classic would you like fries with that)
BOGO offers-- with advanced logic...

You may think, "Shopify already offers this..."
Not even close.

MERCHANDISING is crucial to customer UX. Just having an offer is not going to help sell anything. You have to communicate it. And let your customer know every step of the way about the offers.

As a merchant who was instrumental in the development of more than a few "best of breed" discount apps and modules, Discount Ninja is clearly the winner.

PS - If you insist on poking around my site -- please know I am also using a best-in-class popup app to help with add-to-cart upsells... IN ADDITION to DN.

[update 2+ years later]
I don't have much to add besides "Discount Ninja for the Win!"
I am now using Rebuy WITH DN for crazy powerful promos, and most importantly, customer UX.
The DN developer continues to improve the product -- OS2 compatible now.
Can I give an app 100 stars?

This app is a lifesaver! If you need discounts to stack, need discounts to not stack, need tiered discounts, need ways to offer discounts to selected groups of people, need ways to bypass Shopify's basic level of discounts... THIS IS THE APP TO HELP YOUR STORE. Easy to use, keeps getting better, great service and assistance from the team!

I have been using this app for quite some time. It takes some time to learn but has a lot of options and configurations. Support is excellent, and they address all of my issues promptly.

Really loved this app! Been using this app for almost a year. It allowed me to promote multiple promotion at the same time and super easy to use even on your first try. Their support team are also very helpful and they reply promptly when you ask them questions! Great job, great team. I have also submitted a feature request. Would love to see more great features in future.

Everything I needed to run promotions!
Support is outstanding, all my questions have been answered quickly and any problem with display has been fixed

I'm very impressed with the fantastic support we've received from the app team! They're incredibly responsive and always ready to help! We've only scratched the surface of all the features available, but we're excited to dive in and explore all the possibilities.

We make extensive use of this app on our site and the flexibility it offers ito promotions is second to none. We've had to call on support a (very) few times and the issues were resolved promptly. Highly recommended.

I use this app for around month now and I am very satisfied overall.
It gave decent functionality during Holidays period.
Customers' support is at a very high level (felt this 100% when some customization was needed).
Recommended!

Discount Ninja is a great addition if you're seeking to amp up your promotions! Their team answers questions and concerns in a reasonable time frame and follow-up until the issue is resolved.
