Who is doing the maths at Asda?

it's early so I could be wrong

0.81 ÷ 102 = 0.0079411...... so for 100g

0.0079411 x 100 = 0.79411!

Making it about 79p for 100g

Can you only hold one thought in your head at a time or something?

Is there something wrong with your eyes, I agree not everyone would post online about it but how would you not be able to see the difference when it's literally right there in front of you?

Except that recent studies have shown this not to be true.

A quick google will tell you that you'd have to eat about 20-30 tins a week for the rest of your life in order to exceed the safe limit of mercury, so I think a couple of tins here and there are likely to be fine.

@stuckinthemiddlewithyou1 - you’d be surprised then! However the product actually ends up on the website at some point downstream a human is creating at least some of that data when they set the product up. Whether the supplier send the data and Asda imports it into their system, or whether they have a team doing product data entry internally, someone has put the wrong number in the wrong box! It’s not great for a customer and @Blondiebeachbabe should definitely raise it to customer services but it’s not malicious (or tactical). Given how many products Asda sells I’d be amazed if they were more than 95% accurate at any given time to be honest

But 6 cost less in total than 4 due to an offer. This is common. Plus, if they didn't want 6 cans, they could have put 2 in the food bank collection.

But their loss anyway.

You should have taken a more aggressive stance. A woman in a Chinese supermarket in Manchester who was of Chinese heritage (we are not) once took some dim sum out of our trolley , took some differently branded but same flavour out of the freezer and swopped them. When we checked they were better value as I think she’d been indicating in Chinese. We smiled and said xie xie .

however your couple may not have had enough dosh for six.

I had enough time on my hands to check the drained weight of those 132g tins of John West tuna. That information is missing from the ASDA website but available from John West.

Turns out after you drain the spring water or the brine out of the can you are left with the same amount of fish 102g per tin. Draining away the sunflower oil leaves you with 95g of tuna. So when you pay the same price (81p) per tin you will get 7g more fish if you avoid the oil.

Can somebody else please do the maths to work out how much 102g costs per hundred gram when the tin costs 81p?

I'm not sure that any of the three comparison prices are correct, 61.6p/100g for brine looks too low, 85.5/100g in spring water (seems most plausible), and 3.49/100g in sunflower oil is bonkers.

The Asda website is completely fucked and has been for weeks on end as they've been 'upgrading' it (and breaking a lot of things in the process). Wouldn't be surprised if this is part of it too.

That’s different, though - it’s not bad maths, it’s active deception on the part of the store and I’ve seen it a lot in different supermarkets. They make something look like a bargain (XXL, ‘value pack’, ‘limited time offer’, etc.), and when you check the price per 100g, it works out cheaper to just buy the regular size. They often do it with higher priced stuff like washing powder & it’s completely fucking iniquitous.

On a related note, I was looking at I think teabags recently and the price per unit was a different unit.
So pp teabag
Pp 100gm
Pp kilo sort of thing, I forget the units used, but they weren't overly helpful in deciding which was cheapest. I've seen that on lots of foodstuffs. Randomly vary the unit used to make it next to impossible to find which was cheapest overall unless you had a calculator or knew how much each teabag weighed.

I once got a bottle of wine from morrisons with a yellow sale sticker on it for £7.99, the label was peeling off and underneath was the original price of.... you guessed it, £7.99.

Was very pissed off.

You would think that this would be some kind of automatic calculation by whatever system manages their website.
An excel spreadsheet with formulas at least!

Im no web site manager (or whatever you call it) but I’d be surprised if this was a human manually inputting these values???

It is advised limited because of the mercury. Why would you eat heavy metal unless you actually want a brain injury.

There have obviously been some data entry errors as most of the tuna shelf is wrong. Also the 125g tins are more expensive than the 132g (in a different tin).

Fwiw, Asda are quite good when you contact them if you've overpaid because of things like this. There was an incorrect shelf label and I got a £3 voucher (price difference £1.50).

On a similar theme, I once complained to Sainsburys about the shelf comparison prices for laundry tabs. There were at least three different sizes of bag. They all told you how many tabs per bag but then some had the comparison price per 100g and some per wash.

OK so I am fairly numerate so I could work the comparison price out for myself with the information provided, but that's beside the point. If they are providing a comparison price it should help you do just that so should obviously be in the same units.

Anyway, giving a price per 100g for something sold in number of units is not helpful.

youre unreasonable for shopping at asda

I went through a diet phase a few years back and bought the share size monster munch because the calories were so low. It said "98 cal per pack" so I was loving life only to see the same cal per pack on the tiny packs you get in multipacks. Turned out they were labelled wrong and inadvertently been shovelling loads of extra calories in my gob 🙈😂 i emailed them and they apologised and corrected it. Hopefully I have saved future dieters from the same error...

The price of these products is the same. Personally I'd only check the price per weight of the overall price was different.

I think a supermarket getting basic stuff wrong like this is important. I buy 80+ items when I do an online shop and am unlikely to be checking whether I've been stiffed on the price with each one. We have to be able to trust major retailers to get this stuff right, they make so much money out of us all every year.

It isn't. You just could do with possibly limiting it. It's a good source of cheaper/easy to use, protein etc for many.

Or she could post about it on here as well, because people are told to read the price per weight. So it's good to tell people that the supermarkets can't be trusted on that.
It looks like they are pushing to sell the brine product, is it a coincidence that in all the health articles we are told to avoid that one?
@User457788 you might not, but disabled etc people often have no choice but to shop online and many have to resort to putting shopping on a credit card. People choose branded thinking higher welfare/less additives etc.
The whole point about our food/trading standards is to make billion pound companies transparent, why posters don't get that is a bit of a mystery.
