That's an extra 20 cents per sticker that you could end up getting. They
apparently sell for .30 AUD each here at the cheapest listing for that sticker
sheet. I converted the cheapest priced listing through xe.com so your mileage
may vary.
Still, a good find! If TLG made that packaging error in a significant number
of sets, you might be able to get a few extra dollars out of it. A bit pricey
just for some extra money from packaging mistakes.
