Yea, it doesn't seem like such huge news to me they're intoducing a new $4 droplet when they had previously had a $5 droplet...and bumping that one to $6.
Even $6 is a lie: they're going to take "taxes" on top of that. One day we'll see a mandatory "tip" field with three choices: 15%, 20%, 25%.
Now they don't have a $5 droplet, which was by name alone basically an important branding asset in of itself.
Carl's Jr used to have a Six Dollar Burger but that's gone now that it would cost ... six dollars. (I guess it's been renamed to a ThickBurger).
