There were a few years when I was a kid in which my family was actually pretty well off, but that was the exception, rather than the rule.
After my little brother was born, money was tight. After my parents split, it got tighter.
My Grandmother worked at Walmart, and had previously done a lot of work with small kids. As a result, we had lots of Boxes. She'd bring home boxes that had held cheese (perfect size for Atari 2600 cartridge storage) and boxes that had held all manner of other things.
These were normally thick chip board, or otherwise not corrugated. The ones that were interior boxes from inside other packaging would also frequently be devoid of printing of any kind.
Do you understand what this meant?
