if you need it this weekend and didnt get any BTO options could cancel the order and go pick up in store
for ***** and giggle i just did a BTO 13" with the 750 hdd and it said delivery with standard shipping would be mar1-3
with a non BTO config and 2-3 day shipping it says 2/28 - 3/3
so looks like no way of seeing one this weekend unless in store
