Reselling items through sites like Ebay, Amazon, and Craigslist is nothing new when it comes to it being an income stream. But the concept of reselling as an investment vehicle is rarely spoken about.
When you purchase a stock, hold for a period of time, and then sell said stock for a profit you're investing... the same process takes place in reselling. For example you find an item at a thrift store, list and hold the item, then sell it for a profit... is that not investing?
With reselling it is common to see an ROI of 50% to even 1000% or more!
The problem is scalability and time investment.
A couple cool examples:
