Parallel imported product from the UK apparently, have tried them before and they were fine.
The chunky's work out to 55.5c each, the regular 62.5c
I did have the catalogue as the main link but it was scraping page 6 instead of page 8 which obviously didn't show the product this post is about.
Nothing else in the catalogue jumps out as a bargain, strange they stashed this actual bargain on the last page.
Roses on "special" too but 225g for 5 bucks doesn't seem all that flash to me. The Kit Kat chunky's at 55c each is about as cheap as they get unless they're free from 711 :)
If they are similar weights to what we have here, the chunky's should represent far better value as the finger packs used to be 45g and the chunky's 60g - but that was some time back before everything except my waistline started shrinking…
