How do I determine my average margins after implementing a Kohls cash back rewards program at my retail stores?

You've answered your own question. Reach out to your prospects with the question, such as "How would you...". Ask what people want then give it to them if you can with integrity and thoughtfulness.

I've been in the picture messaging space for a while now with my apps Lutebox (voted one of London's top ten most loved apps) and now Click Messenger. I've written a few articles about the space including a recent post about the Future of Mobile Messaging. Snapchat started out as an app called Picaboo, which pretty much did what it does now (prior to the latest update with chat and video calling). They quickly rebranded but saw a little uptake in user numbers and had quite low downloads for several months. Then around Christmas 2011 one of the founders' mom had told her friend about the app, who told her kid and her kid basically then spread the word throughout their high school in L.A. That was what really blew up their download numbers as it spread across teenagers at local high schools. As far as I know they didn't advertise in the early days, relied solely on word of mouth. Also it is assumed that they have a solid user base. Comparatively speaking, their user base may be in the low tens of millions, which may a great base of users, but nowhere even close to being as big as Facebook or Twitter. I'd be happy to speak about this in more detail or about the picture messaging landscape and what I believe to be the future of mobile messaging.

Hi! I am owner of an ice crean chain with 45 stores in Chile. We have stores in shopping centers, streets and also karts that you can put in events and parks. The average cost margin of ice cream (depends on the amount of materials you use in producing the ice cream) is around 40%. This is italian gelatto where you serve the ice cream without a specific measurement so your costs can vary due to the size of each portion you serve. About the brand you should focus on your unique value proposition and what kind of ice cream you are selling. We import the pastry from Italy and the fruits and milk from our country. Your ROI depends on your sales price and costs. If you focus on high market ice cream you can charge high and keep costs down.

Your best bet to get traction quickly in USA is to advertise on mobile ad networks. You may need to advertise on CPM/CPC basis instead of CPI if you have a paid app so make sure you understand your user lifetime value and watch conversion rates closely so you don't overspend. That said, depending on what your niche/vertical is, there are many other ways to market non-gaming apps.

Hello! Aside from the typical website platforms, I would recommend using Twitter's hashtags and user handles. Try following and using the ones that your potential prospect or otherwise ideal partners would be following and start sharing about your work, your progress, and outreach for a potential partner. If possible try to be local when doing so. But obviously, some to use include Startups.co, Basecamp, Inc 500, yesPHX, BetaBulls, MPV, Lean Startup, Lean Methodologies, TechCrunch, etc.
