Solar knight supporter pack confusion

Supporter Packs are able to be upgraded to through plain Point Packs. Up to 80% of the total value of a Supporter Pack may be upgraded to from existing Point Pack purchases.

This means that if you were trying to upgrade to a $100 Supporter Pack, up to $80 of previous eligible Point Pack purchases could be used to reduce the cost of this upgrade down to a maximum of $20.

Supporter Packs within the same series are able to be upgraded to for the difference in cost between the packs.
