It seems very common in M+S, where in the small beer sub-aisle they are often running a 3for£x offer alongside a separate 5for£y offer. Identifying which products are elgible is not always clear. Woe betide if you realise at the check-out you've picked something ineligible ie the discount hasn't applied. On self-scan check-out the discount doesn't register while you're scanning products, IME it's applied when you click 'Finish and Pay'.
I was buying 5 bread rolls at the supermarket and they were 30p each with an offer of 4 for £1. There followed this conversation at the checkout
Clerk: "£1.50 please"
Me: "No, there is a 4 for £1 offer so that's £1 plus 30p"
Clerk: "But you're not buying 4, you're buying 5. 5x 30p is £1.50"
pause
Me: "OK, I'd like to buy 4 rolls please, let's put the other one to one side"
Clerk: "£1 please"
Me: "Here you are. Now I'd like to buy that other one"
I'm not sure to whom the eye-rolling in the queue behind me was directed.
