> That’s where the first R comes in. Only buy as many Pringles cans as you can reuse. People don’t want to do that either, though, because Pringles are addictive. That may be the root problem.

The first R is already not an option, people who buy pringles want pringles, otherwise they wouldn’t be buying that. Short of making pringles illegal you’re not going to change this.

> There’s no way they’ll sell Pringles in bags though; they’re way too delicate for anything but a purpose-built rigid container.

Pringles were literally invented because potato chips were too fragile at a time when shipping bags of chips and having them survive the transit was basically a bad bet. Chips remain sold in bags to this day.
