Got email from cakewalk. it states I am eligible for the $199 - $149 = $50 upgrade to lifetime updates but the system is only offering me the $199 price...... what's up with this?

youd be better of asking here

you know better then I how many cakewalk products you have bought, how many upgrades you have bought
(which please don't list them all)
what you have bought is the deciding factor on what your price is for the lifetime upgrade price.
not sure where you got 50 from though, that's not an option for anyone. as far as I know 99 is the lowest price.

This is the excerpt from the email cakewalk sent me:
....................................................................
Pricing/Availability

The regular price of upgrading from SONAR Platinum to lifetime updates will be $199. Since you renewed already this year, your price will be $199 minus the amount you paid when you purchased your renewal.

Limited-time Offer: Lifetime Updates will be available only through August 31st, 2016. Act now to secure your Lifetime Updates.

I will have to call them tomorrow to see if I can get some clarification
