Drop shipping is fairly similar to running an affiliate store. You act as the mediator without ever touching the product. The difference between a drop shipper and affiliate is that the sale with drop shipping websites is not completely managed. You might have to set up systems to automatically make a purchase with your drop shipping company, in order for it to be sent directly to the end consumer.
Before having my own website, I spent time reading websites, newsgroups, bulletin boards and forums about the game, and eventually started trading online. Back before search engines were any good most of my time was spent in particular Magic newsgroups, some that talked strategy, and some that were focused specifically on trading and/or buying and selling cards.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
