Amazon doesn't need to turn a profit, this is both good and bad. It's bad because smaller companies can't compete. And many of these smaller companies do more for the community than Amazon does. Good luck calling Amazon for help with picking a sensor. It's good because if you return stuff you'll save money with Amazon. Like the times I buy things outside of Amazon I'm amazed to see I can't return it, of the penalty for doing so is like 40% of the item cost.
