That's true, I'll give amazon some credit for trying their best to make returns easy, but it's still obnoxious when the number of cheap counterfeits and poorly made products is so high. No matter how easy they make it, the time and frustration involved with doing without while you wait for another roll of the dice is high.
Online can't quite match on the immediate gratification factor. If you hit the magic sweet spot of things in the right warehouses, you can get some things in a few hours, but if I go to a in-person store, there's no guessing.
If it's wrong or faulty, I can get an immediate replacement or refund rather than waiting on a RMA process.
