I’m finishing up Better Together 2.0. The feature list is different from what I initially announced:
- add_cat_to_prod will be added as a supported linkage.
- category id handling will not change – it will remain as is (i.e. CAT means master category); I had considered a change here but decided against it.
- the cart will be sorted by price so that using the most expensive first item and the least expensive second item will be chosen (yielding the lowest discount). In practical terms, add_cat_to_cat(x, y, …) or add_prod_to_cat(x, y, …) will select the least expensive item matching category y, rather than the next category y item in product_id order as is currently done. This is the behavior most people expect since it’s the most common retail implementation of BOGO (”Discount applies to lowest priced item.”)
