The shopper wants a total they can trust
Free shipping works as a price presentation because it removes a late variable from the buying decision. The freight still exists. The question is whether the merchant accounts for it before showing the offer or surprises the shopper after the cart already feels complete.
Baymard reports that 39% of ready-to-buy shoppers who abandoned during checkout cited extra costs that were too high. For furniture, appliances, and other big-ticket products, the answer is not a blanket promotion. It is a cart-specific decision built from the shipment and the order economics.
Start with the costs the offer must protect
A defensible offer begins with the merchant’s protected margin floor. Product cost, a trusted shipping-cost estimate, payment and variable fees, and any chosen reserves are carried into the same calculation. The remaining headroom is the maximum offer the cart can afford—not a target the system must spend.
- Use current product cost rather than MSRP or a zero placeholder.
- Use a practical parcel or LTL plan rather than the cheapest theoretical rate.
- Expose every cost and reserve included in the calculation.
- Withhold the offer when a required input is missing or untrusted.
Make the honest price the conversion strategy
BigCommerce itself cautions that free shipping can damage the bottom line when the cost is not built into the product or order economics. Ship Safe Offers turns that warning into a repeatable decision: understand the cart, build a practical shipment, price the full cost, and apply the margin rules.
The shopper receives a simple offer. The merchant keeps the calculation, assumptions, and reason the decision was allowed.
