#9 #7 #8 Not bad. Like the more square feel of #9, but do like the $ "s" inn spend. Not sure on use of all caps in #9, but wouldn't mind seeing a variation. Also, on the tagline, we want to see it as two distinct phrases, finished with a period, ie. "Tell a friend. Get a deal."
#9 and #8 seem to be like a hand with a megaphone. Interesting concept, but would be interested in a slightly turned megaphone with more of a 3D feel--just an idea. Also, not sure about the color of the megaphone...perhaps it could be blue. On #7, what about a dashed line around the item the hand is holding...sort of signifying a coupon?
Very open to other ideas as well. But out of what's been received thus-far, these are the best. Don't like the $ on the megaphone. Could maybe see some money coming out of the thing, but not just placed on the side.
