I always wanted to buy it, but by the time I saw the first ad, it was a lot more than $7. As the years went on, the price kept going up on a regular basis; it felt like the price increases far outpaced inflation. Here’s one article, there are a number of other articles you can find – http://secretfunspot.blogspot.com/2007/12/polaris-nuclear-sub-photo.html. Glad I didn’t buy it. Some of the articles are a lot more vocal on the subject.

I don’t know if any child drowned using this toy, but cardboard plus water is a bad combination.

I wanted one, but by the time I saw the ad, it was no longer $6.95, but $49.95, later raised to $79.95. Never could raise it and think my parents would have not allowed me to purchase it. There were plenty of comic book ads that promised a lot more than you got back then.
