I haven't seen them myself in the shops, but apparently tins of toffees have turned up in Countdown supermarkets (which is owned by the Woolworths company, so they might be in those branches in Australia). I was given a tin by somebody, who told me there were two different ones, but only one is mentioned on the Star Wars NZ forum where the image was "borrowed" from...
The Stormtrooper helmet is slightly embossed on the lid from underneath with various levels, giving a minor 3D effect. The 15cm diameter (or about 6in for those still using ye olde measurements) tin contains a plastic bag with a measely 10 individually wrapped toffees ,,, so the price of about US$3.90 for the tin is a bit excessive on a per-toffee basis.
The label on the back of the tin says:
Toffees - Made in Mexico
Tin - Made in China
Imported by Park Avenue Foods Pty Ltd, Australia
No wonder they cost so much. They've travelled more than I have!
I've also been told that there is a small
My Little Princess desk calendar at the annual Calendar Club stalls that pop-up for the Christmas season. There maybe be other Star Wars calendars coming, but the computer was down when they asked the person running the stall about others (last year there was only one wall calendar).
