WattleSupplements

The app works for what I want. There is a restriction for shopify discounts applied on top of the volume discounts that is a bit of a downer as it doesn't work with shopify discounts that are specific to certain customer segments / customers but "work aroundable" for my needs. At least, this is clearly flagged as not supported so, people just need to keep it in mind. The support is very efficient - Extremely quick (I never waited for longer that 5 min for a real person to get back to me) and they genuinely made the effort to address my queries.

Have been using it for a while now. Multiple options to fit budget and works great. Besides that, I always had a good experience with their support team
