Hmmm .... how about a 12 days of Christmas contest?
Each day for the 12 days leading up to Christmas Day:
*Have people make (1) post in the contest thread (more than one will disqualify) Each of the 12 days use random.org to choose one post # and that person wins either an extra nice % off a future order or maybe a prize that will have been posted for that day.
*Have people post their order invoice number for orders placed in December then on each of the 12 days prior to Christmas you can random.org one of those numbers and that person can win a prize.
