Yes you did it is "Don't put all your eggs in one basket." That is why I have multiple vendors that I buy from.
The theory behind tariffs is make the items more expensive so the local items can sold better. As said it is a theory but when our local companies also raise their prices it just makes the ones with tariffs look good again.
I do agree Aussie and American are better product but most consumers still fall the lowest prices without any regards to quality and then bitch like heck when they get stung. I do buy at the best price I can get for a quality product but that is not the same buying the cheapest item. Believe me their plenty of crooks out there so you got to do your homework before buying even then you can get burn every once a while by those OEM products that ships an aftermarket product.
