Hey!
Our store is trying to implement a tiered discount based on spend and found the below script which executes fairly well for us. The problem that we’re running into is that it allows a user to enter in a discount code at checkout that stacks upon the existing discount. I’m wondering if anyone has an example script where a single discount code is required in order to execute the below. The other alternative would be for us to disable entering in a coupon code altogether when we run a promo like this, however we would prefer to track this + allow users from other channels (e.g. ambassadors) to be able to use codes that have a higher % off:

# Tiered Discounts by Spend Threshold
#
# If the cart total is greater than (or equal to) an entered
# threshold, the associated discount is applied to each item.
#
# - 'threshold' is the spend amount needed to qualify
# - 'discount_type' is the type of discount to provide. Can be
# either:
# - ':percent'
# - ':dollar'
# - 'discount_amount' is the percentage/dollar discount to
# apply (per item)
# - 'discount_message' is the message to show when a discount
# is applied
# ================================================================
