Given an attribute of type
Date, I know it's possible to create a catalog price rule based on math (=, >, <) for a given date. What I'm seeing if anyone knows about, is if it's possible to create one based on compound math.
Catalog Price rule:
Custom Date <= 30 days <
so given today is
2014-12-15 , the rule would apply all products with a
Custom Date of 2014-11-15 or earlier
