Shopping cart showing shipping cost at checkout

Short answer: shoppers form a price in their head from the product page. When delivery, taxes, or fees appear later and raise the total, many feel misled and leave. Show delivery cost and time as early as the product page, state any free-delivery threshold everywhere, and keep the total visible. To confirm it is your problem, look for exits immediately after the shipping cost first appears.

Why the Surprise Hurts

It is rarely the amount. A shopper who expected to pay ₹999 and is shown ₹1,148 at the last step reacts to the change. It feels like the store held something back, and it restarts the decision at exactly the moment they were ready to pay.

The same applies to taxes added late, "handling" or "convenience" fees, and cash-on-delivery charges.

Surveys of online shoppers consistently place unexpected extra costs at or near the top of reasons for abandoning a purchase.

Measuring It on Your Store

Find the step where the delivery cost first becomes visible, and measure the drop there.

deepsync("track", "shipping_cost_shown", { free: false });

Then compare:

ComparisonWhat it tells you
Completion when delivery is free against when it is chargedThe size of the effect
Exit rate at the step where cost appearsWhether surprise is the cause
Orders just above and just below a free thresholdWhether the threshold changes behavior
By region or pincodeWhether specific delivery zones are a problem

A funnel with "shipping cost shown" as a step makes the drop visible.

What Recordings Show

Watch sessions that left at or just after that step.

  • A pause at the order summary, then exit.
  • Scrolling up to re-read the total.
  • Going back to the cart to remove an item, trying to reduce the cost.
  • Adding items to reach a threshold they have just learned about, sometimes giving up.
  • Looking for delivery information earlier, on the product page, and not finding it.
  • Entering a pincode and getting no result, or an error.
  • Opening the returns or delivery policy page and not coming back.
  • On mobile, the total is off screen when the shipping line updates, so the change is discovered only at payment.

Where to Show Delivery Information

PlaceWhat to show
Site-wide bannerThe free-delivery threshold
Product pageDelivery cost and estimated date, ideally by pincode
Product card"Free delivery" where it applies
CartCost, estimated date, and progress to the threshold
CheckoutThe full total, always visible, before any payment detail

Principles:

  1. Never reveal a cost for the first time at the final step.
  2. Show a date, not a duration. "Arrives by Thursday 9 October" is clearer than "3 to 5 business days".
  3. Let shoppers check their pincode early.
  4. Include taxes in displayed prices where that is the norm for your market.
  5. Name every fee, and avoid vague "convenience" charges.
  6. Keep a sticky total on mobile checkout.
  7. If delivery is unavailable to a location, say so before the shopper fills the cart.

Free Delivery Thresholds

A threshold can increase order value when it is clear and reachable.

  • State it early and often.
  • Show progress in the cart: "Add ₹240 more for free delivery".
  • Suggest items that would close the gap.
  • Set the threshold a little above your typical order value, so it is a nudge and not a wall.
  • Apply it automatically. No code required.

Watch for the downside. If many shoppers reach the cart, see the gap, and leave, the threshold is too high or the delivery charge too steep. Compare order completion just below the threshold with just above.

Consider building delivery into product prices if your margins allow. A higher item price with free delivery often converts better than a lower price with a charge, because the total matches expectations.

Find the first moment a shopper sees your delivery charge

Walk your own checkout on a phone and note the step. If it is after they have entered their address, it is too late.

Key Takeaways

  • The surprise causes abandonment more than the amount.
  • Measure the drop at the step where cost first appears.
  • Show delivery cost and date from the product page onward.
  • Make thresholds visible and automatic.

Conclusion

Shoppers will pay for delivery. They will not forgive being told about it at the last second. Say it early, and the total at checkout becomes a confirmation, not a shock.
