Amazon also did this with diapers.com

They are notorious for doing this.

it's a known behavior of theirs[0]. sounds plausible to me.

You don't think it's believable that Amazon sells something truckers would use?

It's good to ask for a link (although not good to give one if this is your friend and it may affect their relationship with Amazon that you're talking about this in public), but you can't expect people to waste time thinking about your ringing ears.

Then don’t believe it and go on with your day. No one owes you a link to anything, especially if you simply don’t pay attention to Amazon’s widely-reported business practices.
