One of the products the company I work for sells is trainings. We are trying to run a sale on trainings in January-March, but cannot get the discount code to only work for those trainings. I know I can add the particular trainings SKU as a condition, but there are over 200. I set a condition that the product in the shopping cart must have a year of 2018, but that isn't working either. Any thoughts?
You can set the start and end date for a cupon/cart rule.
