Apple's annual Holiday Return Policy just started. This enables you to buy any product from Apple now and return it up until January 6 2019 for a full refund, provided it is still in new condition.
https://www.apple.com/au/shop/help/returns_refund
"For products purchased from the Apple Online Store between 14 November 2018 and 25 December 2018, we will accept returns until 8 January 2019."
Applies to any products (not just Apple products, but excluding gift cars obviously) purchased from Apple's online store or Apple physical stores.
Still in new condition….
I suppose that means it should be unopened and still in the box. Not a trial if you dont even power it on
