To help reduce the pressure of choosing options and changes to orders, I have split the group for Kepler into two parts.
"Kepler" secures your preorder spot.
"Kepler - Options" defines your kit options.
If you would like to reserve your spot but choose your options later, checkout with "[PREORDER] KEPLER" in your cart. You will be allowed to change your "KEPLER - OPTIONS" and any additional extras until the deadline.
