Minimum Cart Subtotal Threshold even if Free Gift is in Cart

[psm9640]

Hello -

This is most likely due to operator error but I can't seem to figure out a solution and welcome any/all input:

We are using a "Buy X Get X Discounted" script to give someone an item for free if their cart is $99 or more. The free gift is normally $30. The problem is that if the person already has this item in their cart and say the entire value of the cart goes to $105, the discount applied to that free gift knocks the overall cart subtotal to $75. Is a BXGX Discount the wrong application here?

Thank you very much in advance -- script generator has been a life saver thus far!
