Update the order list.
Please note that if you fill in the reddit or DT, you will in the order list over there.
If you order kit 1 + kit 2, I will change your order as kit 3. That will reduce 1 USD for you.
If you order both kit 1, kit 2 and kit 3, I think you only need kit 3, So I remove your order for kit 1 and kit 2.
Please let me know, if I am wrong with your order and invoice.
