As you're out and about doing our weekend shopping, you can keep an eye out on unique products that are appealing to you or anyone else around you. Also, look in stores like Khol's or Bed Bath & Beyond. These places have all sorts of products in the market that people are willing to buy. If you see something that is really cool, see if people are buying it online, like Amazon, as well and see if you can make a profit with that item.
