Ok I know this has be a repetitive question by alot of people. But, I ordered a 15in MBP 2.66ghz this Tuesday May 25th around 2:00pm EST. Everything is standard/stock except I had Microsoft Office installed, will this slow down my shipping? They said: "Ships: 1 - 3 business days, Delivers: May 27 - Jun 3" and it is "prepared for shipping". Depending the time of month or what ever, when do you guys think I should receive it? I really need it before the 30th of May, is it possible? Thanks for your help guys.
