Turn Shipping Simulations into Smarter Pricing & Bundling Offers

January 16, 20267 min read

Most e-commerce businesses charge shipping based on weight-based rate tables or carrier API pricing. While this approach covers fulfillment costs, it completely misses the opportunity to turn shipping optimization into a competitive advantage that drives additional sales.

The Problem with Weight-Based Pricing

When you quote shipping costs purely based on weight, you're leaving money on the table—and missing a chance to delight customers with savings. Here's why:

  • Weight-based rates assume the worst case—each item ships separately
  • They ignore the dimensional efficiency of combining products
  • Customers see no incentive to add more items to their cart
  • You can't identify which product combinations actually save money

The Simulation Advantage

By running product combinations through Ship-ify's packing API, you can discover exactly which items fit together efficiently. This isn't guesswork—it's data-driven insight into your shipping economics.

What Simulations Reveal

Multiples of Same Product
Buy 2, save on shipping

Discover how many units fit in one box. If 3 items fit but 4 requires a second box, you know exactly where to set quantity discounts.

Complementary Products
Bundle deals that make sense

Paper cups + matching lids? If they share a box efficiently, offer a 20% discount and still save on shipping.

Building Smart Bundling Offers

Here's how to translate simulation data into revenue-generating bundle offers:

  1. 1
    Run your product catalog through Ship-ify. Test common product combinations and quantities to map out packing efficiency.
  2. 2
    Identify "sweet spot" combinations. These are bundles that fit perfectly in one box when purchased together but require multiple boxes if shipped separately.
  3. 3
    Calculate the actual savings. Compare the cost of shipping items together vs. separately. This is your margin for bundle discounts.
  4. 4
    Split the savings with customers. Offer discounts that pass on part of the shipping savings while keeping the rest as increased margin.

Example: The Paper Cup Bundle

ScenarioBoxesShipping Cost
Case of cups (separate)1 box$12.50
Case of lids (separate)1 box$8.75
Total if shipped separately2 boxes$21.25
Cups + lids bundled1 box$14.80

Shipping savings: $6.45. Offer a 20% discount on lids ($1.75 value) and keep $4.70 as increased margin per order.

The Virtuous Cycle

This approach creates a powerful feedback loop:

Lower Costs

Fewer boxes, lower shipping fees

Higher AOV

Bundle discounts increase order size

Happy Customers

They save money and feel smart

The bottom line: being smart about how shipments are bundled and packed saves money. Those savings can be passed on to customers to drive additional sales—creating a competitive advantage that compounds over time.

Getting Started

Use Ship-ify's API to simulate your top-selling products in various combinations. The insights you gain will reveal bundle opportunities you never knew existed—and help you build pricing strategies grounded in real shipping economics, not guesswork.
