After much searching in several stores I can safely say this is the best value deal (the most balls for your money), so long as you are looking for a variety of flavours. Also comes with (?) handy tin. Might also be useful as a giant cookie cutter.
Works out at $3.30/100g which is much better than what you would get from official stores.
I would try to calculate the price per ball but I need to get out more…
Woolies is an unofficial store?
