Like it or not Amazon is the everything store. Damn near every single thing you can buy can be found on Amazon.
I doubt anyone can recommend an Amazon alternative, so my next question is who should I use as my "Smile" nonprofit?
Ideally it's a BASED company that won't piss money away on some bullshit.
Hard to compete. Amazon doesn't make any money from their retail operations, it's entirely subsidized by AWS.
