DualDiscount lets merchants create customer-entered discount codes with two percentage rates. Variants where custom.promo is true receive the promotional rate; variants where it is false or not set receive the other rate. Merchants can set a minimum spend, exclude products, variants, and gift cards, and target all customers, B2B customers, or customers without a configured customer type. Multiple codes can be created, edited, and managed directly in Shopify admin.

• Apply separate discount rates to promotional and standard variants.
• Target all customers, B2B customers, or customers without a type.
• Set a minimum qualifying spend for each promotion code.
• Exclude selected products, variants, and gift cards from discounts.
• Create, edit, and manage multiple promotion codes in Shopify admin.
