Like #47 best. Would like to see if we can flip "No" to sideways though. In this one and the others I am not keen on the "no more promotions" all being the same color as people could potentially see that stand out, What about "SayNoMore" being the same color and promotions being the other color? Then maybe the exclamation point is one color for the long part, another color for the dot? Not sure if it would look to busy, but would like to see it.
Also like #54. Not a fan of serifs though, can we see it with a smoother, non serif font? Maybe not so sharp on the edges of the exclamation point either.
Great job on these though!
