I spontaneously grabbed the marble roulade in Bern-Westside today because it had a special offer sticker on it. Unfortunately, I didn't realize until I got home that the normal price of CHF 3.60 was being charged. I couldn't find a sign on the shelf (it was a special table with promotions only) telling me what percentage off the goods were, but I trusted the round sticker on the packaging.

This is a product that I only treat myself to occasionally when it's on promotion, otherwise I can do without it or wait for the next promotion (about three times a year is enough for me). So I'm all the more annoyed that I've been "caught out" again, even if it's only a franc at most. It's simply not right to mark items as being on promotion when they are not. When I got home from shopping, I fished the latest M magazine out of the letterbox and immediately checked to see if it might be a promotion that doesn't start until tomorrow (even then, it wouldn't be right to mark the goods today). But no, no roulade promotion in the magazine. Not even online.
