Ah, I got it. A reduced price is better than upgrading for what you already paid. I agree.
You'd RATHER have Savings/Refund ...Agreed ! But to Smokey's original point , If Plan A: having that refund is NOT an option , And Plan B: taking advantage of the opportunity to upgrade for free IS an option , Does that not then become a good option ?
Edit...Hadn't read Another_Critic response . sorry for the repitition
