There was a product in Australia in the 80's called “Lolly Gobble Bliss Bombs” which used Ghostbusters in their promotions for at least 3 or 4 years. Bliss Bombs are like honey-coated popcorn that come in packets similar to potato chips.
From about 1986 they had the GB logo on their packets, and among prizes you could win were RGB figures and merchandise. I won two Egon's from collecting Bliss Bomb coupons, hehe.
Up until 1990 I was still seeing “Ghostbusters” Bliss Bomb packets in the supermarket from their mid-80's promotions. But I'm afraid they are long gone now.
