Ow, i didn't mean to offend you by questioning prices, i'm sorry if i did, it is because of my English

.In fact i am very appreciated for this guide, we pay 1/3 price for the same game thanks to you

.
I just want to find cheapest one. I guess cheapest one is the battle.net for now, but as i heard it takes 72 hours to make your account ' playable ' . What if we buy the battlechest for 99 ruble from the battle net and WOD from the plati.ru for 825 RUB, is my account going to be active instantly or do i have to wait for 72 hours too ?.
Note : i understand that cheapest value for the wow+wod is now 750-825(WOD) + 99 (WOW) Rubles= lets say 1000 RUBLES. My aim is to activate my account instantly after buying the game.
