#4 impacted me for my send away Boba Fett. He was supposed to have a firing rocket pack. Collected the necessary tokens and waited (like in Christmas Story) for it to arrive....except it didn’t fire....they did include a paper explaining why... I was a very ticked young lad.
The only thing I ‘sent away’ for as a kid was a package of Boyers Mallo Cups. They are like Reeses Peanut butter cups but filled with marshmallow cream.
Each one you buy had a small card inside with a number of ‘points’on it. When you saved up enough ‘points’ you could mail them in for a ‘free’ case of Mallo cups about a dozen or so.
Mine came in on a very hot Mississippi day and stayed in teh mailbox all day. They were melted into one big blob.................
