Two recent orders for the same build - placed on the same day within 5 minutes of each other.
NewEgg - UPS 3-Day, $22, arrived on the third day in excellent shape, left on back porch as requested by note.
ClubIT - FedexSaver, Free, arrived on the fifth day in excellent shape, left on back porch as requested by note.
Only real difference I saw was the tracking on the UPS site is updated much more often and timely than the Fedex tracking. Then again, the Fedex was free.
