I don't think people buy on Amazon because it is the cheapest, they buy on Amazon for convenience. EVERY SINGLE TIME I buy something from someone else (talking online here) I painfully regret that decision (didn't arrive on time, didn't arrive at all, shipped in multiple shipments, one arrived, two didn't and yet order is showing as delivered -> this is just small sample of what I have seen just in the last say 6 weeks). My wife and I have been trying all year to purchase as much as we can on other e-commerce websites but in often (always) ends up like these examples above...

Harbor freight also has much more consistent quality and no fake name brand items. It’s funny because they used to be synonymous with low quality- but now they seem to have the highest quality tools you can easily buy as a consumer.

We are taxed for road repairs. It's a common tax on gasoline here in the United States; and, yes, there is a known issue around this with electric cars and some efforts in place to try and rectify it.
