Stack Discounts Pro

Top tier app

Does literally everything we want it to, and much more. Very, very powerful, and it displays the stacked discounts at cart and checkout. Allows you to select product variants, not just products, and allows you to select exclusions. Easy to use, fast UI.

Feature requests as of this review:
- Export and import campaigns. We have tons of products, so we want to apply volume pricing to hundreds of variants
- Explicitly explain to customers when an exclusion applies: At cart and checkout, show 'This item does not qualify for ' would be cool - and an auto-generated list of exclusions as a url or popup would be even better.

Just wow - great execution
