I've recieved packages on Saturday from Newegg and UPS but I always order overnight shipping..
Once NewEgg processes your oder, and you 'track your order,' it'll say when its scheduled to be delivered.
If you were to order now, even with overnight shipping you wouldn't get it tommarrow because its too late for NewEgg to process it. Ussually if you want it the next day, you should have it sent in before 1PM PST.
All the same, good luck..
