I came across this at the Martin Place Lindt cafe..
All hello bars 39 grams are $1 a bar, save $1.50. Slightly better than half price.
Offer is possible available at other Lindt cafe stores.
I did not ask how long this promotion runs for or when it ends.
These bars was located through the store in at least 3 different places. Side table, on the window still and on the front counter.
Not bad but have always thought these bars are over priced. Your image link is full of spam too btw
