As a matter of fact… I hardly believe it myself.
I bought it immediately. Right now, this second. It was somehow stupid (*) to do, but I didn’t want to risk that it goes away in the next minute again. I even downloaded it immediately, just to make sure that it doesn’t go away from my account history…
Thank you DAZ, Thank You! 
(*) So why was it somehow stupid to buy it immediately? Because I wanted to buy it with all other “iconic shapes” and that would be close to another $50 which gives a $5 discount.
I was paranoid in the past and thought that maybe DAZ will release a “complete iconic shapes” bundle one day and add S4 as an extra. And thinking back to some things that happened, this idea was probably not that paranoid after all. So I didn’t buy the Gen3 and Gen4 shapes yet.
And now… they accidentally removed the discount for the Gen3 bundle (!!!).

Up until last night, it was 50% (the discount started with the Gen5 sale, but now terminated with the Gen4 sale). The 3 individual couples inside are still on sale, so now the bundle is more expensive than the total amount of all contents…
This obviously is a glitch, and I’m sure they will repair it in time. But do I want to risk losing S4 again just because it’s been taken off the shop again? No! Never!
