Do you know if that was mostly Eastern Canada? I don't remember ever seeing those.
As kids, we loved Pot of Gold. The chocolate caramel cubes reminded me of that.
They changed the boxes at some point in my teens and they were no where near as good.
The fruit ones were our favourites - cherry, orange and it was either strawberry or raspberry.
Lately it's Purdy's instead and they came out with new flavours sometimes in the last 10 years. Don't know why they do not put them in the standard box. Fingers crossed next year I will be up to doing some custom boxes, from what I remember it's the same price but need to go when it's not to busy and they have the loose stock to do it.
