Growing up here in Southern Arizona, I can honestly say from 82-88 no one was a peg warmer and everyone was. When we were kids, there was no army building. Many kids only wanted/needed one of each figure. Most parents wouldn't buy multiples saying, "You already have one of those. What do you need another one for?" When we had our great battles, you had to keep reusing the soldier or viper you just killed. Didn't bother us much. That's what imaginations are for.
With that in mind, it wasn't unusual to walk into the toy aisle any time of the year and be able to find the figure you were looking for. That was one of the best aspects of have waves cover an entire year rather than a quarter. If it took me a couple weeks to a few months to save up my money for a Joe purchase, I ride my bike to the store and pick up Snake-Eyes, Dusty, Vipers, etc. without having to worry about what the scalpers might have missed.
When it comes to buying toys, that's the aspect I miss most from the 80s. There wasn't a rush to grab everything new as soon as it's out for fear that you'll never see it again. You could patiently plan out your purchases over the course of the year.
Case in point, every new case of figures that show up here (Walmart, Target, K-mart), Flash is always missing.
Since I can't and won't camp out every morning hoping to find him, I'll probably break down and buy him online.
