Startup Idea : GiveMarket

I have yet to decide if the market itself should be online or physical, perhaps both. But when you buy something you pay maybe 75 or 50 percent to send one of that same product to someone who needs it (i.e. Third world country, homeless shelter). The app could be an online version of the market itself like Amazon but it would also tell you where the nearest GiveMarket is if youd rather physically go. The really cool thing is that the market would carry goods from all over the world! From America to Europe to Japan, together we can end world struggle!
