Sometimes you will find items where the people who listed them were not
very careful about how they listed them, with no picture, terrible
descriptions, no reserve, and other obstacles that have stopped people
buying. These can become a real bargain for the smart investor. By buying
these items at the right bargain price, and then advertising them properly
with good photos and descriptions, it is possible to resell them at a
substantial profit for almost no effort. Another good idea is to sell things
on behalf of other people who, for whatever reason, do not want to sell it
themselves.

Purple scarves are surprisingly popular.

You just agree to take a mutually agreed upon commission.
Checking out church fairs, garage sales, antique fairs, estate sales,
opportunity shops, and auction houses, you can often find all manners of
stuff being sold at a bargain price. These types of things can bring good
sale on eBay (or any other similar site). After just a few easy sales, you
could potentially double or quadruple your money.
