As a lad...model kits were sold EVERYWHERE!!! And there were so many annual kits to choose from, it took me a while to pick which one to spend my 'ALLOWANCE' on!
Now, finding model kits requires a drive in the car, or an internet connection! And, annual kits are unheard of.
But, back then, there wasn't much in the way of aftermarket parts, be it resin, or photo etch, or turned metal parts from a mini lathe.
Today, I try to use a modest amount of aftermarket stuff to enhance what I build, even if I'm the only one that will ever see it! LOL
And, a lot of that is due to the consistent purchase of the modeling magazines down thru the years, and joining the many forums that have come and gone, too.
