I ordered from BB, but I did so via the online system in store (crazy yeah but I live just a few blocks away). The girl at BB said that there was no guarantee of them being available in the store on the release date, and I just cannot leave it to chance. I'd rather wait a day or two and know for sure that I am getting the bundle. I know myself, if I don't have assurance I will spend the next five weeks in worry mode.
I am the same exact way. I spent a solid week in anxiety mode before I secured my preorder.
