I think i understand what you are describing. That the threshold to meet the promo criteria is required to be met while you have your cart discounts instead of the non-discounted price; this cuases you to need to add more products to reach that level. But then, because promo and discounts do not stack, your discounts are removed.
I am just a long-time customer turned consultant/"rep" and have no special access to the website or ability/authority to access orders or accounts etc. (all for good reason as the source protects your privacy) so I only can see what you or any other customer can see. I am not able to look into this further myself.
I just sent Frank (
@Pharmacom Labs ) a message to let him know about your concern. It is the weekend now so it is not likely he or any techincal staff will be around for a couple days. If i do not hear back from him or see him post here, I will reach-out to him again on Monday.
My appology if this is not enough help but it si teh best I can do with the limitted access / authorty I have. I just sent Frank a massage and will follow-up Monday to try again.
