These listings can seem a little confusing since the wording isn't always consistent. That's one of the downsides of selling on a shared listing on Amazon. Sellers can only suggest changes and wait for Amazon to approve them.
It might be easiest...
That's not Amazon's problem to fix. You should send a link to a specific seller's product listing instead if that's really what you're attempting to share.
No, it's nothing like that.
Amazon is simply trying to show the best possible deal in the buy box at any moment. You're jumping to conclusions here, and maybe being a bit too pedantic about Amazon for whatever reason.
