You can only have one edition per account.
This means though, that you can have GvE, Mac Edition, and Collector's edition, which all come with a free month as well as assorted in game items. And these end up costing less than if you were to buy the item packs by themselves.
In fact, in some cases, the net cost is even a negative amount. 
You can apply only one CoH AE Edition code to your account. You can buy the other booster pack separately, if you chose the Cyborg pack with AE, you can still purchase the Magic pack separatley.
Alrighty, thanks I was wondering. Good thing I didn't waste my money. Guess i'll just have to get a credit card.
Its kinda unfair to the people who don't have one. I can't buy any Booster Packs at Best Buy . . lol
You can get a prepaid visa debit card without going through a credit ap.

Also, most banks set you up with a debit card that you can use when you open a checking account, so long as it has a charge card logo on it, you can use it as well.
PlayNC.com also accepts PayPal, which can debit directly from one's checking account.
I was in best buy the other day and bought the CoH Architect Edition, I noticed it came with a free little booster pack + a free month. I was wondering could I buy another CoH Architect Edition and claim the other booster pack as well as the month?
