You really didn’t, actually. The $300 you’d pay to get Cubase 7.5 is discounted due to you being a previous customer. It’s been 5 years since you shelled out, and you are getting a 40% discount compared to new license.
In any case it’s the same old thing. Vote with your wallet. If SB can’t sell the software at a given price they’ll lower the price.
IMO, The price of DAW software is so incredibly low compared to the olden days of hardware that it’s a non-issue entirely.
Of course you will. Just as you would at the supermarket and the gas station.
