Hi, Just a quick question. I've never pre-ordered DVD's on amazon (usually buy at Best Buy) and was thinking about doing so for the Star Wars trilogy as I'm going to be out of town the release week and would like to crack them open as soon as I get home. When do the preorders on amazon get mailed out? Is it not until the actual release date or a few days earlier so they arrive at the homes on the release date? Or is there a certain shipping selection you have to make (ie not supersaver for free) to get it on time?
