Ebay was the very first work at home thing I found to do. I have been selling on eBay for about 12 years now. It is amazing! I list the kid's clothes that are in great shape, books that I finish, and anything else I can find around the house. It is really fun to watch the price go up and see how much money you can make on it. This is a great way to earn a bit of extra income. Anytime money is short, I think to myself and figure out a few things to sell. My daughter knows if she wants a new video game that I will let her sell one she doesn't play anymore and spend the money for a new one. It works great!
If you have larger things to sell such as a bed, try out craigslist. I sell a few things on here and it is pretty simple. Just make sure you are careful since you will actually be meeting the person you sell the item.
I am trying to get back into listing more things on eBay. I have listed a pair of pajamas, a book, and a coat this week. It is pretty easy to learn. Make sure you add a picture to anything you list. You can check out the way I list things on my page. Check it out!
