I went down to the local Tesco today and stocked up on the Palmiers, found them in the section near the cereal bars. The offer isnt labelled although I did notice that the label with the price was red unlike the other yellow ones.
One thing to note is, you must buy and even number of each to get the bonus. I did a trial buy and bought 5 pesto and 5 cheese thinking I'd get 5 lots of 100 points, but no such luck just 400pts. You live and learn
I even said the wife was pregnant and had a craving for the things to avoid any potential checkout shame!
