Unless you actually need it...
Listened to a rebroadcast of the Yvon Chouinard episode on "How I Built This" last night - it's a good one (they're all good ones).
He says "Don't buy our products, repair old ones", and I love it because it's a frequent topic of conversation here in our office.
When one of us is looking over a typical Back-to-School Shopping List, you'll hear "They don't need THAT! - FIVE comp books? NO. Nope. That's too many" - "Who needs a dozen pens?!"
I think a typical business would be thrilled to see those lengthy lists = $$$. They even push add-on sales with offers like "buy two get one free!".
We're marching in the opposite direction. Your kids don't need all that stuff. It will not improve their education, it will not make them smarter, faster, brighter, or happier - but it will 100% add more everlasting garbage to the surface of the earth they're inheriting from us.
With plastic literally coating the earth (from nano to microparticles on up) documented on Mt. Everest and in the Mariana Trench - found in ocean water, fresh water, bottled water, tap water, air, soil, in scaly, furry, humans and animals.
Buy less, and buy thoughtfully.
