Affiliate Marketing Secrets

I’m curious to know if anyone has ever tried using your Local Craigslist to Sell deals you get from eBay or Amazon. The only problem I find is: knowing an item which has great demand but have a higher chance for a local to ring and pick-up that item, I think it highly depends on the ‘saturation’ or how many peeps covers your CL (Craigslist) area.
Not even that but doing the same in eBay or Amazon but I don’t like to bother coming and packaging for shipments. Niche items like a Laptop or an iPhone? What are the chances? Have you done such?

a couple years ago I was part of an affiliate network but I forgot the name… some the businesses involved were like ebay … amazon.. mastercard.. anyone know? thanks so much.
