The problem
Itemized shipping charges shown late in checkout are a well-documented cause of cart abandonment, but folding shipping into price only protects margin if the average cost is modeled accurately across your order mix.
Step-by-step guidance
1. Calculate your true average shipping cost per order
Use actual data across your order mix — weight, size, and destination — not a single representative package.
2. Build that average into your listed price with margin intact
Add your average shipping cost to your product price rather than absorbing it outright, so heavier or farther orders don't erode margin unnoticed.
3. Re-check the average periodically
Your order mix, carrier rates, and package sizes change over time — the built-in shipping cost should be revisited, not set once and forgotten.
Common questions
Does this approach hide costs from customers unfairly?
No — it simply presents one all-in price instead of a separate line item, which is a common and transparent pricing structure, not a deceptive one.
What if my order sizes vary a lot?
Consider tiered pricing by product weight/size category rather than one flat built-in shipping cost across a very different product range.
