I try to avoid chocolate nowadays. When I do indulge I always feel cheated as all chocolate bars have shrunk to less than half the size they were in my childhood. This further helps me avoid all the fat & sugar involved. As a post script the peanut butter ones are the best (lol) (lol)
She took a pic of one IN TESCO'S though which is what threw me off.. I'd ask which one but I know I wouldn't be close to it
Biscoff ones are imports from Dubai found in independent off licenses. Not the big named ones. They are really good too... These are my favorite as well. Widely available in in B&M and Morrison's as a 4x pack for around £1
I saw them (popcorn ones) in my local b&m for 20p reach. Delicious!
One Stop and Tesco. I've seen and bought them in there in the last two weeks.
