Who is doing the maths at Asda?

My understanding is that its done on purpose to make comparison more difficult and to influence the shoppers choice of item. Comparable products often have one listed as "price per 100g", one "per item" and another "per pack". No accident.

There are accounts on social media that point out anomalies like this- 1 for £2, 2 for £5 is a popular one 🤔 Or things like usual price £8, sale price £7.99

You don't quite understand how a forum works, do you?

Don't eat tuna. It's full of mercury.

My local supermarket (not uk) is terrible for this. I always look at price per 100g or kg or litre etc. But now I have to work it out with the calculator and its really annoying.

Although it was funny once when shopping with my DS and explaining prices to him. I showed him that we wanted 2l of orange juice but it was cheaper per litre to buy 2x1l (same brand). The shopper next to me paused, checked the labels, then copied us 😁 Thing is, the OJ changes prices literally every couple of weeks where we live so I have to check it every single time 😔

Wtf? You have so little going on your life that you are applying to a thread that you don't give a shit about. We all know who is a loser here!

But actually, you probably wouldn't be looking at those three tins side by side, its more likely you'd be comparing the branded tins of tuna in brine with the own brand in brine or whatever. So it might cause you to think these were cheaper overall than Asda own brand tins even if the overall cost was more (I always look at the price per 100g to figure out which is the better value).

Someone posted a picture on our local FB page of some multi-pack cans of coke on 'offer' in Asda reduced from £8 to the new cheaper price of £8.80......

You can be on a budget but have some slack in it and your money can go significantly further if you do check prices and buy multipacks, we're not talking about the minority who have no spare money whatsoever.

Plus when you get into the swing of it, you buy different things each week. It's just a matter of buying the tuna one week, soup the next, then the beans etc and buying a rotating stock of multipacks that work out significantly cheaper per item than buying one each of tuna, beans and soup each week.

It should be correct yes, but the vast majority of people on a budget don't check them. It doesn't matter if the price per 100g is cheaper on the larger product if you only have enough to pay for the smaller one. Commander Vimes boots.

Cool. I'd love to have enough disposable income that I didn't have to choose each item in my grocery shop based on which variety is the best value, so... 🤷🏼‍♀️
OP, Asda is the worst supermarket for this IME. A one-off I would chalk up as an accident but it's so prevalent there that I can only assume it's deliberate.

It says the weight is ‘net contents.’ Presumably all the cans have a standard weight to work out transportation/carbon footprint etc. The price per gram is presumably the weight of the tuna only minus the water/oil/brine. Worth checking with them though.

It is quite interesting (can’t be bothered to search all the listings though) because presumably you are getting more tuna for your money depending on what preservative you want it stored in.

OP, just contact them and point it out. I doubt many people do look at price per gram, though it should be correct. Technically it is misleading pricing, but I think you should give them a chance to correct it.

Given all the issues ASDA are experiencing at the moment, this is probably the least important issue for them. It might be annoying but if you went in a store you'd probably understand more. My local asda car park has been shut for days due to ice, they normally clear the snow but I guess that's another cost cutting measure.

This.

I have lots of spare time but haven't yet been reduced to this thank God 😂

Wow they’re all standard price too.

In the example you’ve given, all the tins of tuna provided are the exact same price so I wouldn’t even look at the per 100g figure, I’d select the one I prefer and move on with my day.

You're right to complain and well done for noticing. I'm quite alarmed to hear it's wrong, as I look at them all the time.

I expected the calculation to be done automatically, so wonder where the error happens.

I think it is because the tuna is part of their "big brands event". Those /100g amounts reflect the normal price.

That might possibly be the case for the sunflower oil one but the one in water is far too far off.

From OPs clarifying post
Tuna in Brine marked as 61.6p per 100g (correct)
Tuna in water marked as £3.49 per 100g
Tuna in sunflower oil marked as 85.5p per 100g

@SoupDragon but the post says it was actually cheaper for the 6 cans than the 4 cans overall.

But that isn't necessarily wrong. If someone has a weekly budget they might not be able to spend the extra to get the "cheaper per can" 6 pack. This is true of many things. You need to be able to afford the bigger packs to get the savings. Along with having the storage

Of course, this particular couple may just not have been good at maths.

Try checking the prices on sweeteners, the price per unit (1 sweetener) can't really be reported without going to 4 or 5 decimal places, but they usually report to 3 dp, so many brands look like they're the same cost.

Sweeteners are the sort of product that would be better priced as £x.xx per 100 items

I remember talking to a couple in Asda and trying to persuade them to get the six pack of baked beans because it worked out cheaper than the four pack they were looking at and they just wouldn't do it. It wasn't that each can was cheaper overall, the total was cheaper!

Yes this, I think the weight might be drained weight, but then brine, oil, water, are priced differently.
