1- Do you really need the e-tag?
No, ignore. Unless you want to be a poephol.
2- I think I read you don't need the e-tag, if this is true how do they charge the costs to you?
They don't charge you. That mail you'll get from SANRAL is just a poephol trap to test how far your balls have dropped.
You trap yourself if you get a tag and pay. Don't.
3- If so what is the real purpose of getting an e-tag, I heard its because you get discounts.
It's to make stupid tax easier for them.
4- Where are the damn prices?
Who cares. If you don't pay it's FREE.
5- Have seen pictures of those e-tags? I've just seen illustrations but for the fact you have to have this damn device hanging in your window
I'll only ever see them in illustrations as well, because I'm not buying one. You should do the same.
6- When is the official date of launch?
That's their business. Like I said, it's FREE.
