Not arguing with you at all just pointing out.

"1) the price was less than my previous upgrade"

I checked my sales receipt on this; of coarse I still have it.

Carrara 8 Pro Upgrade: $119.97

Platinum Club Discount: -$79.98

So full price for the C7 pro to C8 pro upgrade was $199.95.

The C8.5 update; that is a .5 update, is just a bit more, like $85.

Facts.
