Was window shopping on ebay and saw some sellers selling iphones, samsung s7s , and etc. I look at how many available they have in stock and it looks like they have over a hundred in stock with sales of at least 10 a day. It gets to me because they offer phones in different colors, data storage sizes, and etc. They aren't the regular dudes that want to sell their old phone on ebay. These guys with the huge stocks are actually shops. If I wanted to get in this niche, where do I get my phones from... specifically iphones? Are they dropshipping? Or do they actually buy from a wholesale supplier? I googled some iphone wholesale suppliers and the prices on ebay still beat those sites I found online. Any info will help me learn a lot. Thanks.
