How does everyone have theirs setup. For example using the stock payment orders total modules how does everyone have their set up.

I have mine as

SUB TOTAL
SALES TAX IF APPLICABLE
DISCOUNT COUPON
GROUP COUPON
TOTAL

Just curiuous how everyone has theirs. I would think there is a starndard format on how a receipt should add up after the total like should a discount come before sales tax or after, same for shipping, etc.

TIA
