How Pricing Rules Work with Existing Product Pricing

MNML Volume Pricing lets you create pricing tiers for individual products, variants and groups of products using Pricing Rules.

If more than one pricing setup covers the same item, the app automatically determines which pricing takes priority.

Which Pricing Takes Priority?

Pricing set directly on a product or variant always takes priority over Pricing Rules.

For example, imagine you've configured:

• A Pricing Rule offering 10% off when buying 5+ items.

• A specific product offering 20% off when buying 5+ items.

That product will receive its own 20% discount, rather than the rule's 10% discount.

It also won't count towards the rule's mix & match quantity.

Priority Between Pricing Rules

If an item is included in multiple rules, the most specific rule takes priority.

Example

You have two active rules:

• "All products" - 10% off when buying 5+

• "Summer Collection" - 20% off when buying 5+

Products in the Summer Collection receive the 20% discount because the collection rule takes priority.

Products outside that collection receive the 10% discount from the storewide rule.

What Happens When a Product Already Has Pricing?

When creating a Pricing Rule, you may see a section called "Excluded from this rule".

This lists products or variants you've selected that already have their own volume pricing tiers.

These items are marked with an "Action needed" badge.

You have two choices:

Option 1: "Use rule pricing"

Choose this if you want the Pricing Rule to replace the item's existing volume pricing.

Important: This permanently deletes the item's existing pricing tiers.

You'll be asked to confirm before the change is made.

The change takes effect immediately, even if you haven't saved the Pricing Rule.

If your rule is still unsaved or "Inactive", the affected item won't have volume pricing until the rule is saved and activated.

Option 2: "Remove from rule"

Choose this if you want to keep the item's existing pricing and exclude it from the new rule.

The item will continue using its own volume pricing tiers.

Products with Multiple Variants

If a product has its own product-level pricing, that pricing covers its variants.

You can remove individual variants from the rule, but you cannot apply rule pricing to just one variant while the product-level pricing remains.

Selecting "Use rule pricing" for the product removes its product-level tiers for all variants.

Any variants with their own separate pricing tiers will keep those tiers.

If only some variants have their own pricing, the rule can still apply to the remaining variants.

For example, a product with five variants might show:

"3 of 5 variants"

The other two variants will appear under "Excluded from this rule".

Note: If you remove one variant from a whole-product selection, the selection becomes a list of specific variants. New variants added to that product later will no longer be included automatically.

Understanding Pricing Badges

You may see badges beside products and variants in the rule editor.

Hover over or click a badge to view the item's existing pricing tiers, including quantities and prices.

The table also shows the regular price, either before the first qualifying tier or beneath the table.

What About Market-Specific Pricing?

If a product has its own tiers for certain markets, those tiers take priority for customers shopping in those markets.

Customers in other markets can still receive the Pricing Rule's discounts.

This means you can use Pricing Rules as a fallback where no market-specific pricing has been configured.

Variant-Level Pricing and Combined Quantities

Normally, a variant's own pricing takes priority over its product's pricing.

However, if "Combine Variants for Volume Pricing" is enabled on a product, the product's pricing is used for all its variants based on their combined quantity.

Any variant-specific tiers are ignored while this setting is enabled.

You'll see a "These tiers aren't used" warning in the variant pricing editor to make this clear.

What Happens When You Add Tiers Directly to a Product?

If a Pricing Rule currently controls a product, you'll see a message in the product's "MNML Volume Pricing" block:

"“<rule>” sets the volume tiers for this product. Tiers you add below take its place."

You can click "Edit pricing rule" to manage the existing rule.

Alternatively, adding pricing tiers directly to that product will override the rule for that item.
