Do it ASAP. I finally saved up $100 to pre order the Limited edition (I wanted to pay for it in full) and I went out to Gamestop today to pre order it but they said that they had ran out of pre orders for the limited edition of Halo 4. So I went to Best Buy and they gave me the same story and so did Target after that. So I went home to do some online shopping and same deal. Even Amazon was sold out. I eventually got lucky and found out that Target.com still has a few Halo 4 limited editions to pre-order. So I ordered one copy from them and got express delivery with it so that it actually gets to my house on Nov. 6th. All in all it ran me about $122.
Anyways if you haven't pre ordered the limited edition of Halo 4 yet I recommend you do so as soon as you can.
