We will refund in full when we can, however this won't be possible if the tree you ordered is over 10ft. You MUST notify us as soon as possible if you want to cancel an order, we won't be able to refund you if the tree has already been dispatched. If you have ordered lights or other decorations it may be possible to cancel your order on the day of delivery, if your delivery zones are A, B or C - you'll need to give us a call to discuss this.
