Final code
# Settings
DISCOUNT_PERCENTAGE = 10;
DISCOUNT_MESSAGE = "Bulk Discount";
MINIMUM_QUANTITIES = 2
# Code starts here
products_by_quantity = {};
Input.cart.line_items.each do |line_item|
product = line_item.variant.product
next if product.gift_card?
if products_by_quantity[product.id]
products_by_quantity[product.id] += line_item.quantity;
else
products_by_quantity[product.id] = line_item.quantity;
end
end
Input.cart.line_items.each do |line_item|
product = line_item.variant.product
next if product.gift_card?
if products_by_quantity[product.id] >= MINIMUM_QUANTITIES
line_item.change_line_price(line_item.line_price * ((100 - DISCOUNT_PERCENTAGE) / 100), message: DISCOUNT_MESSAGE);
end
end
Output.cart = Input.cart
