Research Pricing (And Set Fair Starting Prices): Before setting prices for each item, research your local Craigslist website and (if possible) nearby yard sales to get a sense of how to price them. Remember that many buyers will try to haggle – so set prices a bit higher than your bottom dollar, but not so high that you’ll scare off first bids. 10% to 15% is a good rule of thumb. Consider bunching low-value items, such as old CDs, into lots of five or 10, or offer x-for-$y deals.
One thing, though, there is a big difference in making an app for Android and an app for iOS, and that is the fact that making an app for Google Play costs just 25$ one-off, making an app for iOS costs 99$ a year, so if you are making an app for iOS, I will recommend you to be a bit more confident about the way you will make money by your app, than if you are making an app for Android.
