Jesse, your enthusiasm for looking at solving an obvious problem is admirable. I don't want to be one to burst your bubble, but there are a bunch of reasons why this hasn't happened so far. Unfortunately, your strategy of give-it-away is basically 'build-it-they-will-come', and access to solutions in this space hasn't been a problem. If, after reading all the recommendations on here about how you'll fail, you still think this is worthwhile to approach -- spend your time understanding the retailer (not the consumer user.) If you can meet the retailer's needs, you're onto something. Spoiler alert: be prepared to learn about how everyone else has tried and failed to do exactly what you're proposing.
