to think that any 2 for £x doesn't mean 2 of the same for £x

[shopping81]

Whilst shopping at one of the big supermarkets I saw various cheeses of the same make labelled any 2 for £x.
I was charged full price. When I queried it I was told I needed to buy 2 of the same cheeses.
AIBU to think she was wrong

If it said 'Any' 2 for £x then that's what it should mean.

It depends. Some offers are strict. The terms of the offer should be displayed nearby.

I think that you were right. Also, there doesnt seem, to be any advantage for the supermarket in doing it the other way.

I think it said any 2 selected cheeses for £x from memory. I personally think she couldn't be bothered to check as they were busy.

If it definitely said "any" - then the clue is in the word. You should have insisted they check.

usually I would think that 'any two' means just that, but if you include the word 'selected' it could mean ant two of a specified selection of cheeses, (generally stickered as such.)

ant -- any.
