There may not be much demand for the products you chose. Are other people selling the same products? If so, monitor their auctions to see at what price people are buying.
If other people are not selling the same products, try using an auction (not a fixed price listing) and start the auction price below cost. This can be used to determine the price eBayers are willing to pay. You will see a lot of $0.99 auctions doing the same thing. Sometimes this starts a bidding frenzy and the price gets bid very high.
I've been selling items on eBay since 1999. Today, it is very difficult to make any real money on eBay unless you have unique products that are in demand. Watch the fees you are paying. After you total up the listing fee, selling fee and PayPal fee, you will find that your cost for selling a product on eBay is between 14% and 18%. IMO, that is too high.
Also, eBay auction add-ons, such as multiple category listings and gallery images can raise your selling costs considerably. Do not use these unless you have plenty of profit margin.
A lot of people have been burned by crooked sellers on eBay. Cheap items sell well, but buyers are generally very cautious about buying anything that costs more than $50.
