Adding category price rules
Thank you for reaching out to us. That's an interesting question! As far as I understand, you're looking for an option to dynamically set the price per square foot depending on how many square feet are ordered, as in this example here?
The Pricing Table described in this document can only be set for each product individually. There's currently no option to set one pricing table for a whole category, and get quantity discount for all products total.
If category pricing rules in Measurement Price Calculator would be beneficial for you, can you please add this suggestion to our Ideas Board?
The more popular an idea becomes, the more of a priority it is for our developers to review.
I hope this clarifies a bit, but please let us know if you have any questions!
