My wife actually used to buy things retail on sale either in discount stores or in outlet type stores and resell on eBay. Sometimes it worked great, sometimes not. Overall it was a lot of work for a little money.
Craigslist is best for local stuff. Be ready for lowballers if you are selling something. Even if you are offering a product for a great price expect people to lowball you.
Yeah, but Craigslist is for people who sell less things opposed to a mass amount. I'm thinking of starting up on Amazon.
there is money in the area. I knew this guy who's main job was simply buying and selling on ebay. He did very well for himself. But in order to make a nice income you have to buy and sell A LOT.
