Apple are doing a great job allowing people to cool-off.
When they announced the Macbook, I was ready to buy, no questions asked! Then, over the last several weeks, I've cooled-off but still wanted one. Now today, seeing 3-4 weeks delivery... I didn't bother. And for those that have ordered the Macbook or Watch, they've all got weeks or even months to also cool-off and cancel.
So many purchases are on impulse and Apple are killing that.
I'm guessing it's not available in-store either if shipping times (in the UK at least) are 3-4 weeks.
