It depends were you are located. I live in NY and I have gotten my packages as early as 4 days and sometimes longer. It doesn't feel like it takes that long.
The order was placed on 29th. The tracking shows the package at "departure Scan KY" so I am guessing it will reach in time.
However I am deeply depressed as I ordered some stuff (including porter 7424XP) from Amazon (Yep I know my mistake, should have ordered from AG) and the status is still showing as "Shipping Soon" with estimated delivery date of Oct 5- Oct 8. Now I know Amazon is a big company which honors its commitments but how they will deliver by 9th oct with free super saver shipping while current status is "Shipping soon" is beyond me. I just hope that it reaches in time otherwise I am screwed
