Exclude Route Insurance From Scripts Tired Discount

Technical Q&A
1

How do I exclude a product (Route Shipping Insurance) from being included in a “tired discount by spend” total?
Currently, at checkout the script applies a discount to the route charge, but I need the script to exclude it and not discount it.

Current Script:

"# ================================ Customizable Settings ================================

================================================================

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

================================================================

SPENDING_THRESHOLDS = [
{
threshold: 75,
discount_type: :percent,
discount_amount: 20,
discount_message: ‘20% off $75’,
},
{
threshold: 100,
discount_type: :percent,
discount_amount: 25,
discount_message: ‘25% off $100’,
},
{
threshold: 125,
discount_type: :percent,
discount_amount: 30,
discount_message: ‘30% off $125’,
},
]

================================ Script Code (do not edit) ================================

================================================================

DiscountApplicator

Applies the entered discount to the supplied line item.

================================================================

class DiscountApplicator
def initialize(discount_type, discount_amount, discount_message)
@discount_type = discount_type
@discount_message = discount_message

@discount_amount = if discount_type == :percent
1 - (discount_amount * 0.01)
else
Money.new(cents: 100) * discount_amount
end
end

def apply(line_item)
new_line_price = if @discount_type == :percent
line_item.line_price * @discount_amount
else
[line_item.line_price - (@discount_amount * line_item.quantity), Money.zero].max
end

line_item.change_line_price(new_line_price, message: @discount_message)
end
end

================================================================

TieredDiscountBySpendCampaign

If the cart total is greater than (or equal to) an entered

threshold, the associated discount is applied to each item.

================================================================

class TieredDiscountBySpendCampaign
def initialize(tiers)
@tiers = tiers.sort_by { |tier| tier[:threshold] }.reverse
end

def run(cart)
applicable_tier = @tiers.find { |tier| cart.subtotal_price >= (Money.new(cents: 100) * tier[:threshold]) }
return if applicable_tier.nil?

discount_applicator = DiscountApplicator.new(
applicable_tier[:discount_type],
applicable_tier[:discount_amount],
applicable_tier[:discount_message]
)

cart.line_items.each do |line_item|
next if line_item.variant.product.gift_card?
discount_applicator.apply(line_item)
end

if Input.cart.discount_code
Input.cart.discount_code.reject(
message: “Discount codes cannot be combined with promotional discounts”
)
end
end
end

CAMPAIGNS = [
TieredDiscountBySpendCampaign.new(SPENDING_THRESHOLDS),
]

CAMPAIGNS.each do |campaign|
campaign.run(Input.cart)
end

Output.cart = Input.cart "

Thank you.

*Tiered Discount not tired. Although I am tired… :wink:

Hi Witmade,

I generated a script for you based on your request. It applies the tiered discount like normal, but it excludes the Route Insurance product from the discount (although it does still count toward total spend). However, that means that you will need to verify one thing first:

After you’ve verified that you can use/modify this script below. I’ll copy and paste the script below as well as attach it as a file:

Hi, Thank you for your help on this. I ended up excluding it based on tag, and just gave route insurance a tag that was then excluded, but your solution would be better as in the future I will need to exclude variants and not just whole products based on tags. Thank you for your help.
