TV Time Popcorn. Home popcorn that came in a pouch, one containe for the semi-solid oil, the other for the popcorn. If you cut off a corner, you could reduce the amount of salt by pouring it out. You squeezed the oil into the pot, heated it, added the popcorn, and viola.
**Milk Shake ** candy bars. A rip-off of Milky Way, with little or no caramel, but they were delicious if frozen.
Lick-M-Ade. Basically, sugared Kool-Ade powder.
Regal Crown Sour Fruits. Came in cherry, grape, lime, and (my favorite) lemon. British candy, quite tart and very good. Do not exist any more. 
Fruit Stripe Gum – Yipes Stripes!
Chocolate cigarettes. No longer made, for obvious reasons. The same with bubble gum cigars.
Fizzies – fruit flavored Alka Seltzer tablets. You ended up with a watery carbonated drink.
Corn Flakes and Strawberries – Cereal with freeze-drive strawberries. They were supposed to turn to real strawberries in milk, but were either soggy and mushy or (if they didn’t soak up the milk) sour strawberry chunks (I actually liked those). Kelloggs also sold Corn Flakes with blueberries and with bananas, which were vile.
Leiderkrantz Cheese – never really had it, but it’s notable in that, not only is it not made anymore, but it is impossible for it to ever be made again (it required a bacteria strain that was in the plant; when the plant was shut down, the strain was lost).
