Can you please explain how can we program coupons to run 3 tier promotion at same day:
• Buy $50 get $4 free
• Buy $75 get $6 free
• Buy $100 get $8 free
We set three different coupons for each tier condition but don’t understand how to program the system to use the second tier coupon if customer change the total amount from 50 to 75 or higher?
