I few years ago I use to have an e-commerce site selling jiujitsu supplies and we did decently for the little we knew about marketing. We would spend $30/month on facebook ads and sell $325. I would call vendors and get dropshipping deals where I would sell their merchandise on my website and they would mail it for us. At this time I could still talk to the owners of the company. Fast forward, 5 years later I am having a much harder time finding companies willing to dropship. It seems that Shopify and Amazon have cornered that market. Alot more e-commerce sites online selling very similar products and websites like Facebook are flooded with all types of vendors from all over the world trying to sell their products.
