Should I tell Tesco I basically stole £300 from them?

Small business I would. Tesco I’d take the win.
Next once didn’t take payment for my sons suit and just charged me for a carrier bag. Never said a word.

Its probably already been written off.
We had similar with Sainsbury's- we had top-up gift cards with 5% off through a work scheme and loaded them up for a big monthly shop - got there to do our shop and the gift card system had gone down and we didn't have any other way to pay. Sainsbury's took out gift card details and said they would take the amount (around £200) when it was back up and running and let us take our shop. We waited - and waited - kept the amount on the gift card for months still expecting it to vanish at any point and it never did!

DH also got a free Musclefoods delivery that was delivered anyway after he cancelled- he rang to tell them and they said just to keep it!

My first thought would be, dam wish I had ordered more.. haha..

see it as a win and think no more about it!!!

Of course you shouldn’t tell them. But I’d be inclined to set the money aside for a few more weeks just in case it somehow gets discovered.

As they've issued a refund already how would you ask them to recharge you?

I wouldn't say anything in this situation

The reason why I wouldn’t tell them is that you cancelled it. You shouldn’t have to pay for a shop that you cancelled. You can’t return the order now and they wouldn’t have taken the actual physical order back anyway. There actually isn’t a way to put this right that doesn’t leave you incorrectly out of pocket.

It would not even occur to me to tell them.

Literally wouldn’t give it even another seconds thought. And you can ignore the PP saying to keep the money ring fenced, there is literally no way they could ever claim it back as the mistake was theirs, not that they’d even bother trying. However, if you are the type to feel guilty about this sort of thing to the point you can’t function, you could make a generous donation to your local food bank

No. Keep your mouth shut
It's their fault. Don't waste your precious time on them.

But you didn't steal it, you did not go into one of their stores and stuff £300 worth of products under your coat and in your pockets and then leg it out of the door. You cancelled it, they did not update their system and the order turned up, there was no intention on your part fo defraud Tesco. Technically it is theft because you have not paid for the things but I would have no qualms abotu keeping the stuff as they should have better processeses . , They are a massive company who made £2.3 billion in profits last financial year, it is not like a small independent business who would be really affected by such a loss.

It’s not the same as walking out a shop without paying.

This was their mistake & it’d be a bloody nightmare trying to get someone in a call centre to sort it. It’s not your job to fix their accounting errors.

I would just leave it and see if they realise. In the past I would not have been able to sleep as I would feel guilty but time has taught me don’t bother. Once I realised the corner shop didn’t scan an item as it wasn’t on my receipt, I only noticed when I got home! I promptly drove back to the store which was 4 miles away with my kids in tow, struggled to get parking and had screaming kids with me to be met with a moody cashier who just ignored me, not even a thank you or just polite conversation! I even posted on mumsnet at the time under a different username to be met with abuse that what did I expect him to do.

No, I wouldn’t. You cancelled it and they delivered by error. Their mistake.

if I’d been the one to answer the door I’d have refused the delivery and said why. But my kids wouldn’t have known to do that and like your DS they’d have unwittingly accepted it.

The thing is though you didn't want the order - you cancelled it - so I don't really see why the fair outcome is that you pay for it, it's their error. Okay so you've used the food and benefitted but I really wouldn't say the onus is on you to sort this out.

They made the mistake. I wouldn’t tell them. They aren’t going to go out of business for it and it won’t effect the persons job. It was probably just a computer glitch and nobody will notice.

The most that could possibly happen is they do notice it and take the money, but I think that’s highly unlikely. It will just be recorded as wastage. They throw out thousands of pounds worth of wastage food out every day (I worked for them), I wouldn’t give it another thought.

Yes I'd tell them... Would you walk out of Tesco shop with a trolley full of a £300 shop without paying?

Of course Tesco won’t care. It depends whether you care OP and if it makes you feel guilty. If it was someone stealing £300 of food from the store, would you feel the same?

I would leave the extra in my bank for a few weeks incase they claim it otherwise would let it go

No

No. Fuck them. They owe it you.
The amount of times they've done me over delivering things that were broken or out of date.. or saying they'd delivered things they hadn't. They owe me 300 quid at this point. So you can have this one on me!! A gift from the gods of fortune!

Hi OP
As someone who recently tried to get a refund reversed from Tesco- apparently once issued its impossible according to customer service.
Different but my driver only showed up with one bag, didn’t realised until we got inside. Contacted Tesco for a refund and was given it immediately contacted them via WhatsApp to reverse it and was told it wasn’t possible.

I would. Back in the day when you could still pay by cheque I paid for my weekly shop and the lady on the till had to call the manager because she had entered something wrongly. There was a fair bit of toing and froing and checking the till receipt. Then the manager rang the groceries through, gave me my Clubcard and receipt and I walked out with my shopping. When I got home I realised he had given me my cheque as well. I rang them and said I would bring the cheque the next time I was in the store. I did so a week later and I was told to forget about it as it had been written off. But I felt better for telling them.

Entirely their error. I’d not be telling them.

On a smaller scale, they refunded the mince I bought saying it had been short dated. It was no shorter than usual, and because we always check it, it went in the freezer. I didn’t tell them.

It was weeks ago and you’ve eaten it. It was a genuine mix up and a drop int he ocean for them. But yeah, keep the money for a bit just in case.
