I just thought of another way to find things to sell on eBay.
Go to your local dollar store and buy one or two items that you think would sell for more than a dollar on eBay, then post them up and see what they sell for. If they sell for more and you see that there is a demand for them buy a couple more. Then if they sell keep buying more until they do not sell any more, then switch to something else.
This way if they do not sell, you are not out too much money.
