To want to name and shame this particular supermarket?

[EscapeInTheCity]

Went to do the shopping today. Bought some cheese with a special offer 'Buy 1 get 2 free'. So I took 3 of them.
Went to pay and realized that I had still paid for 3 cheeses.

Asked customer services who found:

• that the offer had expired the day before
• that the new 'price' for the cheese was different (and lower) than the one advertised on the offer.

Which annoyed me to say the least because:
1- there must have been quite a few people this morning who bought that cheese thinking there was a special offer on and they didn't benefit from it.
2- They had actually inflated the individual price just for the offer just to put back down once the offer was finished (so it has never been a 'real' buy one get 2 free).

So Shall name and shame this big supermarket?

OP, if they overcharged you they should have given you the item free and refunded you double the difference between the price you paid and the offer price. That's the policy they advertise. There's a big group of people on the MSE forum who find those errors and exploit them.

So really, your store got off lucky.

I avoid bogoff offers. They always put the prices up before the offer so they don't lose out. It's disgraceful but I doubt anything will be done. I realised in tescos, the money I 'saved' is actually half of what I wasted ifyswim. I now shop in morrisons who have less offers and I actually spend less as I'm not tempted by all those bogof traps. For example tescos cheese offer sounds good but the cheese is a fiver for one when that cheese is always on special offer for £2-3 pounds in other supermarkets.

I think they like to keep it complicated. All those offers make it really really hard to see what's the best choice - there can be 7 different ways to buy oranges, in bags, not in bags, in bags in 2 for 1 or 3 for 2 offers, in other bags, and on and on and on. The harder it is to decide, to see what's best, the more people make a more expensive choice than they would otherwise. Factor in changing the prices in time, too, and I have absolutely no doubt that they have hired people to optimise our confusion levels to maximise profits!
I figure: if I want a slightly more pleasant shopping experience and can pay for it, I do (either by accepting less choice, when I go to a local shop like the lovely Turkish ones we have around us, which have great fruit, veg, breads very reasonably priced, or through paying more when I go to Waitrose for nice cheese, chocolate, wine etc etc) I really dislike shopping in all the major supermarkets for this reason. And if I really must have many many nappies, toilet paper, breakfast cereal and all that: online shopping rocks.

"My local shop with a T was recently selling packets of white sauce at 40p each or 2 for £1"

Could you not have made them swipe the additional packet so you could pay for it separately from your main shop, thus saving avoiding the additional the 20p? I'd do this, but I am known to be cantankerous.
