I just noticed I skipped a post by not mentioning that between the time period when I posted we had 6 1/2 hours to go and were in the #8 spot, we slipped to #13 by 6:00pm! So I did go buy those 2 liters I was talking about for the "power codes", 75 to be exact. Those codes pushed us to the #3 spot at 9pm!
Well, we did officially finish in the #4 spot and I have already been contacted by Pepsi to complete my paperwork, which is due June 10. I submitted it at 3pm today :)
Thank you to all who supported us in this endeavor.
