I currently have two products that are available to be ordered individually or through an auto-ship (subscription). They belong to the same category.
At first I only sold products individually and created discount codes for them as well to various websites. I like it this way because it gives people good incentives to get large orders and try the product for the first time.
I then added the auto-ship options under the same category...meaning the same category discounts and coupon codes still apply. This was all fine until recently one customer repeatedly keeps using old coupon codes for the auto-ship products (which are less expensive) and ends up buying the products for less than what I make them for.
If I want this to stop is it as easy as assigning a new category to the auto-ship products with their own category discounts? Or is there something else I need to do?
