I have to thank @avgjoegeek geek who pointed out to me on Facebook that he noticed Punchtab had a snapshot of "Featured Giveaways" for the Punchtab iOS app in iTunes and 2 of my giveaways were listed in their screenshot.
The Lenovo Z585 Laptop giveaway back when it had only 12k entries was listed as well as my Kingston 64GB DataTraveler giveaway which has since ended and Alan Tong was the winner.
But, now that I see this this only makes me realize this is a great feature that Punchtab has that Rafflecopter does not. I can literally get an app that shows Punchtab contests and pick and join which ones I want to join without having to do Google searches for Rafflecopter contests.
If you like joining contests and maybe getting lucky to win something, there is no reason not to check the Punchtab Giveaways app to see if something you like is being offered that you just may win.
