Dianne I remember the mixed bag of lollies for 20cents too. We used to take forever to pick which lollies we wanted in our bag for 20cents as well. It must have driven the shopkeeper crazy but all the kids used to do it. My favourites were:

Jelly Babies (sugar coated)
Teeth
Milk Bottles
Pineapples
Bullets
Strawberry and Creams
Sherbies

I also used to love Choo Choo bars and Toffee Apple bars but they were 10cents and a bit too expensive for me most of the time!
