Online Auctions and Drop Shipping
You can make "decent" money at online auctions. The most popular is Ebay. Make sure you pay attention to all the fee's and calculate them in. For example there are listing fee's, Final sales fees and Paypal fee's. As long as you calculate these expenses into the transaction, you will have no problems. One secret is to add a little to the shipping fee which isn't affected by the hidden cost.
Another problem people have is merchandise. That isn't a problem. Sunrise Wholesale Merchandise is an online company that will sell from there inventory over thousands of products. Registration and membership is free and you do not need to upgrade to make purchases. Free drop shipping makes it even more convenient.
You can sell smaller items such as Beanie Babies. I have gotten as much as $5 but its best to auction off starting at 1 penny and add $3.99 s&h. Shipping fee's are not effected by the hidden fee's and the 1 penny produces no final value fee. You are actually left with a profit.
Also keep in mind, you will need funding to pay for the items as Ebay can and usually will freeze your Paypal transaction waiting approval of the customer!
