Ok, I'll explain more, but I expected you guys to know more about DreamHost , I'm just a newbie here and it seems I know more.
I made my web ID: you can get money referring other people, you can get donations, you can get gift certificates or whatever. Your account will become positive in balance - Nothing bought yet, nothing ordered yet.
Now I did some of these methods, and when I had enough money already there I make the decision to use the dreamhost to host my sites. Ok , so I think I want to order L1 plan. In my Panel I see the option "Add plan", as it is my first order ever I say to myself - I can use this link , there is no need to log-out, then to go the main page, choose the plan, LOG IN again (cause I already have the web ID)... It seems logic doesn't it?
Well nope! If I choose the "Add plan" from my Panel (what I have done and I am crazy now - 19h and no answer) I CANNOT use a promo code.
BUT, if I would LOG-OUT, go to main page -> choose a plan -> LOG IN -> I could use the promo code.
This seems pretty silly in my opinion. And I have calculated the amount I can pay including this promo code, which I should be able to use.... now I have a negative balance, no one knows what I am talking about here and support has no response from about 19 hours. I'm getting insane here cause I don't get this...
