Product Bundling for Wholesale: Pack Sizes, Cases and Assortments

Quick Answer

Yes, pack sizes, cases, and assortments each need distinct pricing logic. Wholesale Pricing Discount B2B supports quantity breaks for case-pack-based volume pricing, custom pricing at the variant level for pack size differences, and collection-wide or cart-level rules for assortment pricing, so each bundling type reflects accurate wholesale economics rather than a simple unit price multiplication.

What is Wholesale Bundling?

Wholesale bundling typically takes a different form than retail bundling, less about pairing complementary products together and more about how a single product gets packaged and priced, individual units, case packs, or curated assortments of variants.

Each of these bundling types needs its own pricing logic, since a case pack price is not simply the individual unit price multiplied by quantity once volume discounts are considered, and an assortment needs its own defined price distinct from summing its individual components.

This guide covers wholesale product bundling through pack sizes, case quantities, and assortments, and how to price each correctly on Shopify.

What Are the Different Types of Wholesale Bundling?

Pack size bundling means a product is sold in a specific quantity per package, like a six-pack, with its own price distinct from six times the single-unit price. Case bundling means a larger quantity, often several pack sizes, ships together, typically qualifying for a volume discount. Assortment bundling curates several different variants or products together as one purchasable unit, often at a price reflecting the value of the curated combination.

Who Needs to Think About Wholesale Bundling Pricing?

• Manufacturers selling products in multiple pack sizes or case quantities
• Distributors offering curated assortments of variants as a single purchase option
• Sellers currently pricing case packs as a simple multiplication of unit price
• Businesses wanting case quantities to reflect genuine volume discount economics
• Companies wanting assortment pricing that reflects the value of the curated combination
• Teams wanting distinct, correct pricing logic for each bundling type they offer

Why Correct Bundling Pricing Matters for Your Business

• A case pack priced as simple unit multiplication misses the chance to reward larger orders
• Assortment pricing that does not reflect a coherent bundle value can undersell or overprice the offer
• Correct pack size pricing avoids confusion when buyers compare per-unit costs across sizes
• This precision protects margin across different bundling types simultaneously
• Getting this right makes each bundling option feel intentional rather than arbitrary
• Buyers comparing wholesale suppliers often scrutinize this pricing logic closely

How to Price Wholesale Bundles on Shopify

Step 1: Prepare Your Store and Customer Tags

Identify which bundling types your catalog actually uses, pack sizes, cases, assortments, before building pricing logic for each.

• List which products use pack size variants, case quantities, or assortments
• Calculate the actual cost and margin implications for each bundling type
• Confirm customer tags and tiers are in place if bundle pricing should vary by group

Step 2: Install and Configure Wholesale Pricing Discount B2B

Install Wholesale Pricing Discount B2B and configure the specific pricing mechanism appropriate to each bundling type, rather than applying one approach universally.

• Set custom pricing at the variant level for different pack sizes
• Set quantity breaks reflecting genuine volume economics for case pack quantities
• Set collection-wide or cart-level rules for assortment-based bundle pricing

Step 3: Create the Pricing or Discount Rules

Build each bundling type's specific pricing rule, confirming it reflects real cost and margin considerations rather than a simple, potentially inaccurate multiplication.

• Confirm pack size pricing reflects actual per-unit cost differences, not simple multiplication
• Confirm case pack volume discounts reflect genuine fulfillment efficiency at that quantity
• Confirm assortment pricing reflects the value of the specific curated combination

Step 4: Test With a Tagged Test Customer

Test each bundling type with a tagged test account, confirming the pricing displayed matches the specific logic you intended for that bundle type.

• Add each pack size to a test cart and confirm variant-level pricing displays correctly
• Add a case quantity and confirm the volume discount applies as intended
• Ask Sidekick which volume discount tiers apply to a specific product to confirm bundle pricing resolved correctly

Step 5: Go Live

Once every bundling type tests correctly, publish the pricing live and monitor orders across each bundle type for accuracy.

• Publish pack size, case, and assortment pricing to your live storefront
• Highlight the specific bundling options clearly on relevant product pages
• Monitor early orders across each bundle type for pricing accuracy

Wholesale Bundling Pricing Examples

Candle Manufacturer (Home goods)
Problem: Priced case packs as a simple multiplication of unit price, missing the chance to reward the actual fulfillment efficiency of a full case order.
Setup: Set a genuine volume discount for case pack quantities through Wholesale Pricing Discount B2B, reflecting real fulfillment cost savings at that quantity.
Result: Case pack orders became more attractive to buyers while still reflecting the business's actual cost efficiency at that volume.

Specialty Food Producer (Food and beverage)
Problem: Offered a curated assortment of flavors but priced it as the simple sum of individual products, missing the chance to price the assortment as its own coherent offer.
Setup: Set a specific cart-level price for the assortment combination, reflecting its value as a curated bundle rather than a simple sum.
Result: The assortment became a distinctly priced, more attractive option rather than functionally identical to ordering the same items separately.

Summary

Wholesale bundling through pack sizes, cases, and assortments each requires distinct pricing logic, reflecting genuine per-unit cost differences, real fulfillment efficiency at volume, and the coherent value of a curated combination, rather than treating every bundle as a simple price multiplication.
