In UK nappies are ultra cheap. My Wife uses Lidl's nappies but Aldi's are equally good (if not the same!). They cost around 5-7 pence each. Can't really exactly remember because they are so cheap.
Pampers are more expensive but by much.
Here is another example from a UK suermarket https://groceries.morrisons.com/webshop/product/Nutmeg-Nappi... which is 0.075 GBP (0.10 USD)/diaper.
The UK doesn't charge sales tax on nappies/diapers - https://www.gov.uk/government/publications/vat-notice-714-ze... which may explain a small part of the difference.
> In the United States, the average diaper sells for about 25 cents
That's so much more expensive than here. Looking at the pictures you can get the same brands and nappies for half the price here.
In the decent sized packs from amazon pampers are only a touch more expensive but yeah the Lidl ones are just as good as far as I can see. We mostly used pampers because they are cheap with a subscription but have used Lidl ones fairly often. Shame we're not very close to a Lidl store (well we are, but traffic).
Seems to be a typical price. At another chain, I get the same prices for another brand. Looking for the biggest A brand, I find 72 diapers for €15, which is a bit more expensive, but still less than 25 cents (though eurocents are worth a bit more than dollar cents, of course).
Pampers Premium Size 5 (35) - €8.99 - €25.5 each
Bigger packs are cheaper per nappy. If you can wait for offers you usually can get the Pampers much cheaper e.g. right now 2 x 72 pack for €23, 16c per nappy.
We started off with Pampers and moved to ALDI, never looked back.
But all in all at 4 nappies a day you'd just break €110 a year with ALDI.
