It's like the geico commercials: you could save up to x% on your car insurance if you switch to Geico.

It says nothing, there are two weasel word exceptions in there.

There's another weasel phrase in there: "Or more" (Switching to Geico could save you 15% _or more_)

So it could save you nothing, or it could save you 15%, or even more. Basically we have no idea what it'll save you, if anything.
