1) Add on to customizations. There is a free shipping customizations that a free shippoing id is attached to any product. The fre shipping id specifies amount of products that can be ordered across all products with same freee shipping id and if the meet quantity the items ship for free.
This needs to be modifed to it will identify items with different free shippig id's and only give free shipping to items that qualify but still charge shipping for items ordered where the free shipping id quantity has ne been met.
Currently all items in box whther qualified for free shipping or not are shipped for free or charged depending on order in basket.
2) Also, there needs to be a feature where the merchant can identify items to be shipped for free at timje of another purchased item.
SO say item a is purchased at that time if the consumer purchases item b, item b is shipped with nop shipping cost.
All of this needs to mix in match and either charge shipping for items that have not qualified and/or do not apply shipping charges for items that have qualified.
