Extra charges must appear early

What it is

The number on a product card is often goods only. Shipping, packing, service, tax, resort fees drip in during late checkout—drip pricing. Show them early means people can see “what else will be due” while still comparing, before “Proceed to checkout.” This is timing of surcharges, not how a coupon strikes through a list price, and not a tender-specific processing fee.

Why it happens

The first number becomes an anchor; later fees feel like extras rather than part of the price. Commitment has already risen toward buying, and sunk browsing time makes walking away harder even when the total now beats another shop’s earlier quote. Partitioned pricing makes the goods price look smaller; adding the drips back is cognitively costly. Later reads as a sneak increase; earlier—even as a range—puts comparison on one footing. Exact shipping needs an address, so “early” is often a range or a threshold, not a fake-precise figure.

Studying it

Compare list prices that include a shipping estimate, shipping revealed mid-checkout, and a service fee that appears on the last step before pay. Use the same SKUs and watch leave and choice on list, cart, and checkout.

Independent variables: first appearance of extras, estimate vs exact, whether the makeup is expandable. Dependent variables: whether list-page choice tracks true total, checkout leave, later sense of being upcharged, whether cross-shop comparison uses one basis.

If the lab writes the total in the prompt, the anchor is washed out; let people start from the card price. Do not invent or paste “X percent abandon because of hidden fees”—detection moves with fee type, rate, and screen. Drip-pricing effects recur in behavioral work; what is measured is timing and anchoring, not one industry percentage.

Where it stops holding

Tax may be legally computable only after address; the list page can only mark tax-included vs tax-excluded. Pickup and virtual goods have no shipping; a decorative zero-shipping line is noise. B2B quotes already itemize; this entry is about consumer goods cards. A payment-method surcharge is known only when a method is chosen—do not freeze it into the list price.

Applying it

• Beside the goods price on list and detail, say whether shipping, tax, and service are included; give a range when you can (shipping from …).
• Under the cart subtotal, list known extras; write unknown ones as “calculated at checkout from address,” never imply the subtotal is payable.
• Never introduce a first-time service or packing fee as the pay button is about to be pressed.
• Verify by showing only the list page and asking “about how much to buy one, and what else might be added.” Failure: they cannot name the fee types, or they first meet a fee in checkout.
