Follow one real product from advert to payment and check where the total price is shown.
THE SOURCED NEWS
The reminder covers more than checkout
The Competition and Markets Authority says mandatory delivery charges belong in the total wherever a consumer price is given, including advertising, product pages and baskets. Optional delivery information must also be clear and timely.
The letter discusses flat basket charges and multi-retailer listings. A price breakdown can still be shown, but it does not replace a clear total. The CMA points businesses to its detailed guidance for different pricing arrangements.
SELLERBUNDLE PRACTICAL ANALYSIS
SellerBundle: test the journey a first-time shopper sees
Choose a popular product and record the price shown in an advert, search result, product card, product page and basket. Then compare it with the amount payable for the same order. Keep screenshots with a date so the person changing the site can reproduce the issue.
Check a one-item order and a multi-item basket separately. Include any delivery threshold, collection option or destination condition you actually offer. Avoid assuming that a note in the footer explains a price seen elsewhere.
SELLERBUNDLE PRACTICAL ANALYSIS
Make the review useful for the person fixing it
List each mismatch with the page address and the intended display. Ask the person responsible for pricing and the checkout to review the same example together. After a change, repeat the customer journey on mobile as well as desktop.
Read the official letter and linked guidance for the arrangement your business uses. This checklist helps organise a review; it cannot determine compliance from one screenshot or establish how an unusual delivery model should be presented.
