Independent has the Cadbury chocolate 100g on sale for $1.69, CO51 has $2.50 cash back when you buy 2, plus I had a personal candy offer for 500 pts for every $2.00 spent. I bought 10 $16.90 received $12.50 back fro CO51 and $4.00 from personal offer, I paid $16.90 and received $16.50 back so roughly .04 cents a chocolate bar!!
