i'm interested in purchasing a mac pro during the MO August tax free weekend. however i will be on vacation the first 3 weeks of august in california. which means i won't be able to receive the mac pro when it gets to me. for those who have experience ordering from the ADC store, how long does it usually take to ship a BTO item after placing order? and for everyone, have anyone tried to have apple hold the order and ship at a slightly later date? i know i can always have the mac pro shipped to school or a friend's place, but i don't feel safe about keeping a mac pro at school or comfortable subjecting a friend to safe keep that box for such a long time... any ideas? thanks!
