Is there a way to set up special price for grouped products? Let's say that grouped product contains 3 simples products and the total price is 150$. How would I go about setting a special price only on the grouped one- for example 100$?
Magento 2 does not allow special price at group product level
Why? because when you do add to cart you will see all products as an individual , if you want to set the special price you need to set at the simple product level.
Hope it will help you.
Well grouped product is a bunch/associated of simple products , so you can not set special price for grouped product but you need to set special price for that simple product which is associated with that grouped product !
Another alternate option is to create a Catalog Price Rules , using this you can give some special price discount on the grouped product - but yes i would personally less prefer this option !
so better is to give special price to simple product only
