Discount using Order Tag

Thank you so much, it worked exactly how it should be no way i could have figured that out, that is the first part.

As for the second part, we changed our mind because the 6 discounts are per member, if you get a group with 2 or more members then we will need to give 12, 18 and so on discounts.

One more request, is it possible to show the amounts of discount on the receipt? if yes, then please explain.

Regards,
Michael
