Read the selected store code
The selected B&M UK product 426306 is Pampers Baby-Dry Nappies Jumbo 84 pk,Size 4. The page displays 9–14 kg and an ordinary single-pack price of£14. This comparison retains that exact 84-count store offer rather than substituting a 44-count Essential or a nappy-pants version.
Do not substitute a 44-count quote
The ordinary derived cost is£14 divided by 84,about 16.66667 pence per nappy. The page also advertises two for£20. That is a conditional two-pack basket,not permission to buy one pack for£10 or a discount automatically applied to all retailers.
Keep single-pack and multibuy separate
The B&M page states availability is not guaranteed in a nearest store and some products are in selected stores. An online product page is therefore not a reservation,live local-stock confirmation or home-delivery promise. No order was submitted or pack received here.
Stock is not guaranteed by the listing
Its protection and pocket descriptions remain retailer claims,not this site’s leak or overnight-use findings. Read the actual pack and maker instructions for the exact supplied version. A similar Pampers name from another size,count or country does not fill an unknown ingredient,fit or use-condition field.
Apply it to the selected purchase
If a local store does not stock the 84-pack,do not replace it with a 44-pack while leaving the£14/84 unit-rate calculation unchanged. A different pack requires a new quote and its own current label.
