Today when I was in Jerusalem I did my annual candy shopping. Yes, I only buy candies once a year, for the Purim Mishloach Manot, food gifts. I always buy by the weight, but the first stores I found were selling the little wrapped candies I like to get at 1 for NS1.
I was curious to see if it paid, so I examined the package to discover the weight, just 30 grams. Then I tried to calculate what weight I would get at the per kilo price. I had remembered something like NS18, which according my my calculations would give me just over half a kilo. That was pretty dumb of me; the price was much higher. Later when I found that all the stores were selling them for NS24. So, let's calculate:
The unwrapped candies are less money, but I feel safer with wrapped ones. I didn't find any price variations, and I didn't have the time to search all over.
