Target products by vendor or tag.
Combine two product conditions with AND or OR.
Exclude products or customer tags.
Exclude items already on sale.
Cap the discount amount per order.
Limit how many items in the order get the discount, and choose whether the cheapest or the most expensive items get it.
Run on a weekly or monthly schedule.
