A product can look affordable until the final checkout screen adds delivery, a payment surcharge or a currency-conversion cost. The useful habit is to compare the amount you will actually pay, not just the large number beside the product picture.
New Zealand’s Consumer Protection guidance recommends checking the full cost of an online purchase, including delivery, fees and currency. This five-number check turns that advice into a small decision routine.
1. What is the item price?
Start with the advertised price, then check what you are actually buying. Confirm the size, quantity, model or service level. A low price for a smaller quantity is not automatically a better deal. If a promotion says “from” or shows a discount, find the conditions before comparing it with another option.
2. What will delivery add?
Write down the delivery cost and the expected timeframe. Some sellers offer free delivery only above a minimum order, while others add a charge at the final step. If an item is needed by a particular date, the cheapest option may not meet the deadline. Consumer Protection says a retailer remains responsible for delivery of an order until it reaches you, so keep the order confirmation and promised timeframe.
3. Are there fees or surcharges?
Look for payment surcharges, service fees, booking charges and any optional add-ons that have been selected. A fee is easier to notice when it is written on the same comparison sheet as the item price. Consumer Protection notes that payment surcharges can appear when using some contactless card payments, so check the payment method as well as the product.
4. Is the price in New Zealand dollars?
If the seller is overseas, check the currency before doing the maths. A number that looks like dollars may not be NZD. Consumer Protection also points shoppers to possible GST, border or currency-conversion costs for some online purchases. Treat the displayed conversion as an estimate until you know which amount your provider will charge.
5. What happens if you change your mind?
Read the returns, cancellation and refund information before you buy. A change of mind may have different rules from a faulty or incorrectly described product. Check who pays return delivery, how long a refund takes and whether the item has exclusions. Save a copy of the product description and your receipt.
Make the decision visible
For two options, write five lines: item price, delivery, fees, currency or tax notes, and return conditions. Then add the first three numbers to estimate the amount leaving your account. If the options are close, quality, timing and the seller’s reliability may matter more than a tiny price difference. If the final total is not clear, pause and ask the seller before paying.
The Fair Trading Act protects consumers from misleading prices and important costs being left out, but a careful buyer still benefits from checking the checkout details. The Full-Price Check is not a promise that an online purchase is safe or suitable; it is a way to make the decision less surprising.

FAQs
What does “full price” mean online?
It means the amount you expect to pay after considering the item, delivery, fees and any currency or tax information shown by the seller.
Should delivery be part of my comparison?
Yes. Delivery changes the amount leaving your account and may affect whether the item arrives when you need it.
What if the website uses a currency I do not recognise?
Pause and confirm the currency and possible conversion costs before relying on the displayed number.
Are payment surcharges always illegal?
Rules depend on the payment and the circumstances. Check the surcharge information before paying and ask the seller if it is unclear.
Does a change-of-mind return work the same as a faulty-product return?
No. They can have different rights and conditions, so read the seller’s policy and the relevant consumer guidance.
What should I save after buying online?
Keep the order confirmation, receipt, product description, delivery promise and any return instructions.
