We have some large product packages for sell on our website, which we do not charge shipping for. We set it up so that customers can also add a smaller monthly product order, which will be charged shipping. Since they just made a large product order, we do not ship there monthly order until the following month.
Everything is mostly working. The problem is it does not appear the future product order is going to be charged shipping, because the orginal order was large enough to be eligible for free shipping.
You can see an example here:
Just add either the silver or platinum product kit to the cart while also choosing the monthly autoship checkbox.
How can I fix this?
