Where do i go to buy Jordans upon realse?

I saw the 2013 realse list with the dates yesterday there are quite a few i plan to purchase but i dont know where to buy them. i prefer to buy online and if they are pre orderable that is even better. i have checked footlocker champs finishline and those type of places and did not see any of the realse info or pre order type of stuff. if there is a site that you know of that sells either at or below msrp and i can order them before or at the time of realse no second hand deal like ebay.
