I like this one the most till now. Can you put it on the website to see how it looks? Also, the pic here shows a young boy, which I think will not be good to call a Dad. So, can you please try some pic of an aged person, who actually looks like a dad.
It's really good, but the hat & mustache is not fitting in the logo some how. Please the below examples: http://maxcdn.thedesigninspiration.com/wp-content/uploads/2010/01/The-Coupon-Junkie-l.jpg http://webcoredesignblog.com/wp-content/uploads/2012/07/logo-design-fab-coupons.jpg http://www.namnum.net/img/portfolio_img/Logo_Design/Logo_Design_Geopon.jpg http://ww1.prweb.com/prfiles/2014/12/19/12756968/GBB_final_all_black.png https://s-media-cache-ak0.pinimg.com/236x/d4/2d/4d/d42d4da2afbcf8643eb48060241a55f6.jpg http://www.chadwhite.com/wp-content/uploads/2013/08/bad-mustache-logo.jpg
I like your design as well. Can you try adding vertical coupon stickers at the back of the logo, like this one does: http://noblestep.org/wp-content/uploads/2014/04/Coupons-logo-big.png & https://2.bp.blogspot.com/-oMWqU8fR...MOzQxuQjyeIlQhcxPHTttZQCLcB/s1600/coupons.png
Pic of the guy looks good..but the logo overall doesn't go well with the site. Can you try with the same font style as the website's H1 & remove the tagline Never miss a deal? Also, remove the coupon which he's holding and put 3-4 coupons vertically on the back like here: https://2.bp.blogspot.com/-oMWqU8fR...MOzQxuQjyeIlQhcxPHTttZQCLcB/s1600/coupons.png
Best one till now. Can you try making the coupon stickers in orange & blue colors (the website's theme colors) alternatively (example: https://2.bp.blogspot.com/-oMWqU8fR...MOzQxuQjyeIlQhcxPHTttZQCLcB/s1600/coupons.png) and show how both these purple & other one, would look on the website. Also, perhaps try putting a hat on the guy & make the size of the coupon stickers a bit bigger? The second coupon sticker can be more prominently shown, I think.
