Hello Kayos.,
This is a shipping error we have been seeing a few cases of recently. In order to make it right for you, I have moved the remaining item into its own order, waive the shipping, and provided a discount equal to the overcharged shipping from the packages splitting up. You should soon receive a confirmation email for this final package.
I'm sorry for any inconvenience this has caused and we'll get this final item shipped out to you. If you have any questions or concerns, please let us know. Thank you!
