Where are the lime chocolates?

I love the lime chocolates...but they are just never in stock in Cresta Centre. I have tried all the chocolates that Lindt have in store, but nothing beats the round lime chocolates. Lime on the inside and white chocolate on the outside. I have come to realize that it is because the lime chocolates are so popular and that the other chocolates will not sell if the lime chocolates are in stock all the time, that there is a shortage of them on the market. The new mango cream ones are nice and well as the the fruit sensations that are newish on the market, but they are not my favourite. I have one thing to ask - where are the lime chocolates?
