Today I bought the M-Classic hard cheese in "special offer".
The rack was labeled 30% promotion. But the cheese itself was marked with the normal price.
Fortunately, I looked correctly at the checkout when I typed it in. Otherwise I would have paid the normal price.
I was the first customer today at around 5pm to report the "special offer". I don't know how many customers bought this cheese for the normal price today! So my tip is to keep a close eye on the promotions when cashing in🧐
