Just a word of warning to others that the free 100gb google drive offer is not valid on used, returned or open boxed items. Any savings you have made on the Warehouse deal will be far outweighed by the subscription fee for additional google drive space.
I got my acer C7 this morning and got the 100gb quickly and easily. Depends if the machine has been registered by first owner. amazon should make this detail available on their site - I was just lucky, but I hadn't considered this when I bought it.
