Script Editor

Very very limited API available, you can control very little. Also you can only publish ONE script per category at once! But I suppose it's better than nothing - just. Also, only Ruby - eww.

If you uninstall the app without deleting the scripts first, the discounts will still be applied as if you have done nothing and reinstalling the app won't help you. Enjoy trying another bulk/custom pricing app and watching the discounts duplicate.
Now I get to spend some quality time with support figuring out what went wrong.

This app is no good it does work at all. Also, Shopify was unwilling to help whom we pay tens of thousands of dollars per year in being a plus multiple websites user of capital, etc member very disappointing I expect more very disappointing

They do not even bother to answer questions. Expecting more from Shopify, when you see what you pay !

It has potential. But, this should come out of the box for shopify plus users.
You have to hire a developer to create something for you.
Also, it's limited to 1 script at the time.
Shopify should really work on the Discount Options and Shipping options on their back end so users don't have to spend more money to hire developers. Specially because their Plus plan prices are going up.
