Deal sweetener

[Julian]

Verb. To throw something extra-cool in the already-existing [good deal], making more appealing.
Its something like what a car-dealer does when offering a vehicle with extra [comforts]... but the items in question are for free.
Deal sweeteners work for those who are truly smooth talkers, and those blessed with a [silver tongue] who
know how to talk a good deal. The difference is: Those kind of folks DO SO MORE than those who BS.
But beware... liars can do it, too, especially in working out a scam.
