That's good advice for any purchase. I did a spark plug change recently on my Super Tenere. When I took out the old plugs (which I'd bought on Amazon), I found out that one of them was the wrong plug. I had checked the plug boxes when I received them, but didn't confirm that the plugs inside the box matched the numbers on the outside of the box. Fortunately the plug worked, and I never noticed any performance issues, but it was still the wrong plug.
Lesson learned: If you're buying from Amazon, make sure you check the order right away, and don't let it sit on a shelf in the garage until the return window has passed.
