Limitation: Unable to exclude full-price variants. This issue occurs only when a product has multiple variants with different states (e.g., sale, full price).

Example: Consider a product with these variants:

• Variant A: On sale

• Variant B: Full price

• Variant C: Sold out

Due to this, the product is included in multiple collections (Sales and New Arrivals). When applying a Volume Discount or any discount limited to the Sales Collection, the discount applies to all variants of the product.

When applying a discount meant for sale variants, it currently applies to all variants, including full-price ones. We can exclude sale variants, but excluding full-price variants isn’t possible at the moment. As a result, the discount is also applied to full-price variants when added to the cart.

How global Shopify websites solve this issue: Some Shopify stores avoid this issue by creating separate products for each variant rather than using multiple variants within a single product. They may use third-party apps to group these products together.

Allow me to explain my roadblock in creating purchase-with-purchase discounts and volume discounts due to the lack of this feature.

Issue: Conflict between PWP50 and Volume Discount due to the inability to exclude full-price variants or include sale variants only.

Scenario:

• Product A has 2 variants: a full-price variant and a sale-price variant.

• Product A is part of two collections: new (for full-price variant) and sale (for sale-price variant).

Discount Rules:

Volume Discount: Buy 2 or more items from the sale collection and get a 10% discount. This discount applies to each individual line item in the sale collection.

PWP50 (Purchase With Purchase): Spend RM250 on items from the new collection and get Product B at 50% off. This discount applies to each individual line item in the new collection.

(Because Regios doesn't have an auto add to cart function so that I created this discount using other auto add to cart app and the app doesn't support to exclude sales variant)

Combination Limitation:

Promo Class:

• Shipping

• Product (affecting each product individually)

• Order (affecting the whole cart)

Valid Combinations:

• Shipping + product + order ✅

• Product + product + product ❌

Each product item can only have one discount applied. Both Volume Discount and PWP50 apply to individual line items.

Problem:

When a customer adds more than 2 units of Product A’s full-price variant to their cart and the total exceeds RM250, there is a conflict between the two discount rules.

Detailed Explanation:

Volume Discount: Applies to the sale collection and provides a 10% discount when buying 2 or more items. This discount is applied to each individual line item in the sale collection.

PWP50: Applies to the new collection and offers Product B at 50% off when the total purchase exceeds RM250. This discount is applied to each individual line item in the new collection.

Conflict:

• When a customer adds more than 2 units of the full-price variant of Product A (which is in the new collection):

• The cart exceeds RM250, triggering the PWP50 discount.

• However, since the full-price and sale-price variants belong to different collections, Volume Discount also applies when the customer increases the quantity of items in the sale collection.

• Volume Discount replaces the PWP50 discount because the system cannot distinguish between the full-price and sale-price variants for exclusion or inclusion. This means the intended discount logic fails, causing a conflict where both discounts cannot be applied as intended.

Urgent Need for Help:

• Currently, the app does not allow including only the sale variant or excluding the full-price variant for the Volume Discount.

Conclusion:

• The system currently lacks the capability to exclude the full-price variant or include only the sale-price variant for the Volume Discount.

• As a result, when both conditions are met, the Volume Discount takes precedence over the PWP50 discount, leading to unexpected discount behavior.
