Will I get Halo: Reach on time?

Depends on where you order it from but if you pre ordered Halo Reach you shouldn't of really needed to pay extra to get it on the release date. I ordered mine from Walmart and I either paid nothing for shipping or .97 cents and it will be at my house on Tuesday, day of release, I also pre ordered Metroid The Other M at Walmart too and paid .97 cents and got it on day of release I the US. So in the short run you could have paid for the bare minimum for shipping and have it on the day of release, maybe.
