Lucky for you I wrote them down. The post that had them is probably pretty deep by now and its just faster this way.
Collectors Edition: 708192010332
Standard: 708192010325
I ordered mine from an EB Games retail outlet. But the SKU's mentions above didn't help me. EB Games is using a different type of SKU'ing method. Whats on my reciept is completely different. I did call the store, but all they could pull up on their computers was the same thing that is on my reciept. Hope you have better luck

In the end it would be awesome to get the CE but if you can only get the standard edition you just miss out on the pretty box (which i could care less for) and the fold out tech tree. Stardock has already mentioned that everyone who buys a copy of the game during the first run, which includes the standard edition, will have access to the CE electronic content.
Hope this helps and good luck to you tommorrow
