This bundle lets you save money on Cine Meter II if you bought the original Cine Meter.
Have Cine Meter? Want Cine Meter II? Use "Complete My Bundle"; it's like getting 80% of Cine Meter's cost back when you buy Cine Meter II. USA example: if you paid $5 for Cine Meter, "Complete My Bundle" will be $4 cheaper than buying Cine Meter II by itself.
Note: if you got Cine Meter with a promo code, you won't save anything, because 80% of free is a savings of $0. In this case, you're better off buying Cine Meter II for $25 than the Upgrade Bundle for $26 (or equivalents in your local currency).
