Bestbuy curiously did not charge tax to me and a friend when we bought a $34.99 live sub from them.
Thanks for the replies, I figured what you guys said would happen would, just wanted to make sure.
Turns out it does not really matter, I picked up one of these cards and got it today. Newegg's delivery is great since I am in the same state as them. Do have to pay tax as a result though, but not a big deal at all.
I do have Auto Renew off, so what I may do is just hold out until I need to activate the card, which considering I am renting the new Gears Of War, will probably be pretty soon. I think I have until April though anyway.
